Strictly speaking, the BROS 400 is heavy, underpowered and outdated. But the cheap grey imports are surprisingly nice to ride – they’re well balanced, steer well and the engine is flexible, torquey and characterful given its 33bhp output. That also makes it legal for new riders on a restricted licence.

Suspension fatigue affects the Honda BROS – new fork oil springs and a new shock transform it. Then you can take advantage of the neutral handling, strong RC30-derived brakes and plentiful ground clearance. It’ll even take sticky tyres, though not in the correct front profile (which affects the speedo reading) – standard sized, modern crossplies are widely available and grippy enough unless you’re a lunatic or a trackday fiend.

Very similar to the Africa Twin engine (specials builders actually fit the bigger 750 in the chassis), the understressed motor pulls from low in the rev range unless you labour it in a high gear. Fuelling is classic crisp carburettor response, though power tails off higher in the rev range. Great around town, and it’ll sit happily at 80mph too. It has a surprisingly prominent and pleasant airbox noise too.

Find a cared for BROS (ideally one that’s been loved and kept dry since import from Japan), and you’ll be astounded at the quality. Deep paint, quality fasteners and lovely finish all-round is nicer than most new bikes – including some Hondas! Understressed engine is unburstable, the chassis is tough. Make sure the eccentric chain adjuster/rear wheel hub isn’t seized, and there’s little else that goes wrong. Specialist backup is available too – new-old stock parts are readily available as well as pattern parts.

Accept what the BROS 400 is - a smart, cheap new-rider friendly all-rounder – and it’s a great bike. It’ll cost pennies to run, and a good one is still a viable alternative to the half-arsed current field of 33bhp bikes. If you’re looking for a hardcore sportsbike then forget it, but the BROS is still a very capable and enjoyable first big bike. Find a Honda Bros 400for sale.

Equipment

Basic - the BROS has a comfy, semi-upright café racer riding position but poor pillion provision. Underseat storage only accepts the standard tool kit, and the tank lasts around 90 miles before you need to flick the fuel tap to reserve. Compare and buy parts for the Honda Bros in the MCN Shop.

5 out of 5 The little bike that can.

Version: Product two

Year: 1989

Annual servicing cost: £80

Let’s give this little roaring twin of mine some background so we can verify how good or bad it is, I purchased this machine 3 years ago for the less than the price of a new games console or the latest used smart phone. With the expressive promise that I will restore it to its full former glory as it had been sat outside since 2006, it had no number plate, the front brakes were treated to a brand new vfr400 calliper and new pads all round, new starting solenoid, fresh fuel, a carb clean and finally a service. That’s as far as it got, and apart from yearly servicing, regular carb cleaning, Cush drives a set of tyres it’s honestly wanted for nothing. Runs like the day it came out the factory. In 2022 it was as my sole transport for around 8 months through all conditions, I have now only just decided to give it the tlc it really deserves as I have now brought another bike to use in the meantime.

The ride is a strange position but loveable. you have the same sit up and beg style you’d find on a 70s retro classic or commuter yet your leg position is well crooked to push your bottom towards the rear of the seat that gives the impression your sat on something much much more sportier. All on a bike that I find to have very similar frame characteristics of an nsr125 which takes me back to my teenage self and having the fastest learner bike on the block. The handling is a tad lazy but very frugal and will put a smile on your face with a good set of tyres, even though it’s completely unadjustable and does feel very cheap and soft on low speed manoeuvres.

Engine 5 out of 5

This little 400 will fool you into thinking it’s something much more, it has torque and it loves to show it off. It’s very much like the bike equivalent to todays highly desired German diesel hatchbacks. It will run out of puff higher up and no, your not going to break any land speed records with it, it’s not a fire breathing race machine either but for the occasional blip off a roundabout or b-road thrashing it is more than enough to make you smile and think “this is the little bike that can”. As much as the little engine is charismatic and punchy, the gearbox is clunky and lumpy, it has a considerable number or neutrals that both appear about as often as fuel going below £1.40 per litre. And it does sound like a cruiser if the baffles are pulled, I preferred it personally with the baffles in because it had almost a baby Ducati tone when strangled. thoes two items are my only complaints. Which is impressive for what one of these lovely capable machines cost.

Please see the previous write up before making any judgement on this. Yes it’s left me stranded in the past. Every single time it’s been carb issues, mainly the main jet getting blocked with fuel tank crud. I don’t blame it conking out and it has always gotten me home eventually. Other than that it’s been incredible, utterly faultless. It feels sturdy and well made. The elf single swing arm is maybe not so light and refined as it’s racing inspiration would suggest. But it is really and exceptional bit of kit.

Value vs rivals 5 out of 5

There’s a hidden curse with these motorcycles, it really is exceptionally good on fuel, around town or on the motorway. But that is a double edged sword because it doesn’t hold a great deal of fuel whilst not having a fuel gauge and will have you reaching for the reserve normally before 100 miles and if it’s anything like mine you do not want to go anywhere near the reserve or the next thing that’ll happen is suddenly stopping once you do get fuel and the bowls of the carb looking like they wouldn’t be out of place at a mudlarking convention, So what helps keep the bike very light, is also the greatest hinderance. The plugs are a nightmare to change, your knuckles will beg for mercy oh and did I mention there’s FOUR across TWO cylinders? The air box is rubbish made from the same grade of plastic that your ub-40 cd came in, the choke cables like to ruin your life too so I used some keihin Harley Davidson blanks, starts fine at all temps, the set screws arnt the worst to get too either. Most other jobs can be tackled by a competent DIY mechanic just please please please do not adjust the swing arm chain adjuster with a chisel. Just buy a fairly generic coil over adjusting spanner and turn it to the required tension with the rider sat on the bike. Iv seen full grown men reduced to tears due to chiselled off teeth on the adjuster.

Equipment 2 out of 5

Okay for equipment I’m going to say bare minimum is praise here, this bike has nothing, the clocks show you speed and rpm which the rpm is generally at least 200 out, it has a red light that comes on when you exceed 65mph and you have your standard array of colourful yet informative dash lights, that is it. By god I really wish I had a fuel tank but I also wish it had adjustable suspension, both can be added with relative ease.

Buying experience: I brought it out of a field where it had sat for over 10 years, I gave incredibly little for it and it has coped with a ridiculously tall order, like I said before this really is the little bike that can. Even more so it has been the butt of most jokes from rat bike to the u boat bike, but still this little fighter starts every time without choke and passes it’s mot every year with no signs of it giving up just yet.

Reliable and trustworthy honda engine. Simple, cheap and easy to run, perfect for getting around town. Will even turn a few heads.

Ride quality & brakes 4 out of 5

Slightly unusual seating - with a narrow fuel tank your knees are almost touching and for anyone over 6ft might be a bit too cramped. Can carry a pillion but it's not ideal for one. Brakes and suspension are okay but nothing special. Can do long distance but it is very lightweight and can swing around in the strong winds. More suitable for smaller journeys - especially A and B roads.

Engine 4 out of 5

For a 400cc, this V-twin engine does its job well. It can accelerate quick enough to beat most cars but struggles with top-end speed. You'll really have to get it revving to get past 80 mph. For what you pay for, it's extremely worthwhile.

Reliability & build quality 5 out of 5

As expected from Honda, cannot fault the engine even with its age taken into account. Find one that's been cared for and kept dry and you shouldn't have any major problems with it.

Not much you can add to the bike. With its small street-fighter style handlebars there's no room to add anything and has only basic clocks with no fuel gauge. Would highly recommend adding a windscreen. Can be customised/modified with some time and effort.

Buying experience: Hard to find one, but if you find one in good condition I would highly recommend buying it. Does everything you need from a sub 500cc naked bike.

I rode a Honda Bros 400cc for my motorbike lessons when I first learned to ride and was so impressed I bought one before I had even passed my test. Compared to the other training bike (a super 4) it was so simple to ride, you just thought about it and the bike did everything you asked. The bike coped fine, however I could tell when I was needing more fuel by the numbness in my backside after 200 miles (one tank full).

it was what I was used to, so seemed good, until I upgraded to a Honda Varadero 1000xl tourer. So no comparison after that. great bike for short nippy journeys, I don't recommend it as a tourer, though it managed it fine if a little uncomfortable. great bike for around town.

Exceptional quality, achieved far more than could honestly be expected from it. Having passed my test, no one told me it wasn't intended for covering miles on. So I got on it and rode, often on camping trips fully loaded but one up. I was on the third lap of the clock 273000k before anyone mentioned it was high mileage for a bike. At this point it was still running fine however the leather on the saddle was wearing through. I would go from Coventry to Aberdeen and back in a weekend ride out, or pop into London from Coventry for a night with friends.

Overall, the BROS rides nicely and is able to cope with more or less any road you go on. even motorways! Luggage is an issue with this bike, however ventura make a mounting kit. It handles well and my front forks are fine and present no serious issues. Both suspensions are a little bit soft but they don't seem to bottom out on bumpy roads. In terms of fuel economy, I get about 51mpg currently . I did replace the original heavy cast Iron exhaust (~5-7kg) with a delkevic exhaust (

Ideally suited to just the rider. Pillion seat and handlebars are quite badly designed and uncomfortable to hold onto. I rarely take pillions so It doesn't affect me If serviced properly, the brakes are good and pretty reliable. General ride quality is good. The bike can adapt to most roads without issue. Fat rear tire increases grip.

Engine 5 out of 5

V-Twin, Good torque, flexibility, and sounds nice. Has twin spark plugs for each cylinder. Very strong, unstressed and reliable engine. Not a super powerful engine by any means but the engine is one of the key things that makes the Honda Bros a reliable and dependable bike if you maintain it well.

Reliability & build quality 4 out of 5

Negatives are that the Bros has fuel pump failures for some of them. you can clean the points or replace this part (depending on the fault) with most genuine pumps from other bikes. My current fuel pump is off a Kawasaki ZXR400 and the pump works with no issues. Positive points are that the bike does not rust very easily as it is mostly aluminium and steel. Any corrosion I encountered was purely cosmetic. Aluminium can corrode lightly but no rot.

Value vs rivals 3 out of 5

I spend about £60 on servicing it each year, £20 for 4 spark plugs, £40 for oils and coolants and other fluids. Fuel economy is about 51mpg which is ok for an old bike with carburettors. It consistently achieves this average fuel economy though. About 190km (118 miles) before reserve. Not wonderful, but I've seen worse.

Equipment 4 out of 5

For the 1990 model onward, the rear tyre size is not being produced anymore so my choice was limited to a set of bridge-stone BT45 tyres where the rear tyre was very slightly wider by about 5 or 10mm. It doesn't affect the speedometer as the speedo drive is on the front wheel of this bike. Not great for luggage. However, Ventura make a kit so a top box or panniers could be attached if necessary.

Love at first ride. Once a new Nitron shock was fitted to the rear the handling was outstanding. It makes me happy every single time I ride it. And the MCN review is totally wrong. It is not at all heavy. The most flickable bike Iv'e ridden

I can pull stoppies on it. A bit hard on a pillion but I re-foamed the seat to make a slightly thicker and wider perch and with a GIVI top box behind it's quite good. Has to have a good rear replacement shock.

A 650 would be nicer but for its size it is adequate in power. The sound is very nice

18 October 2010 by will5628

Have been riding mine for just over 2 months now and I absolutely love it. It's pretty much ideal for me as they cost peanuts to buy and run and I'm limited to 33bhp for two years. Of course its not all that fast but having come up from a Suzuki TS50, it goes like a rocket in comparison and the low-down grunt is addictive. Handling's fun too. Its even relatively comfortable over distance, although high speed motorway riding can be tiring if windy. Don't be put off by high mileages as the quality is fantastic, mine has done over 47,000 miles and still looks great and runs brilliantly. As charlesq says, you'll get way more than 90 miles to reserve, I've managed 120, and it cracks 100mph without too much trouble. Can't recommed it enough.

This was the first bike over 250cc that I ever rode, and I remember thinking as soon as I pulled away the first time, "This is a proper bike." It isn't mind-bendingly quick but the engine is full of character with a nice little kick around 7000rpm, the ergos are focused enough to give a gentle introduction to sport riding, and the handling is a revelation if you're only used to standard 'learner' bikes. It's also reliable and parts are still easy to find as it shares plenty with so many other bikes (Revere, Africa Twin, Deauville). Highly recommended for a new rider -- in fact I can't think of a better bike if you're on a restricted licence -- and fun even for the more experienced. The cafe racer-ish looks and single-sided swingarm will make you feel cool, it's torquey and unbelievably narrow so perfect for commuting, and despite what the review above says you'll get well over 100 miles to the tank unless you're thrashing it. Don't be put off by high miles because the engine's virtually unbreakable. One of the best -- and best-made -- street bikes Honda have ever produced, in my opinion. The 650 (Hawk GT in the US) is even better, but rare in Europe.
