The Triumph Speed Triple is one of the second generation of Hinckley Triumphs that, in the late 1990s, really put them back on the map. The Speed Triple is essentially a naked, upright, ‘streetfightered’ Daytona, but it’s a surprising winner that’s not only brimful of bad boy character, but also manages to employ the wonderful and unique 955 triple motor into a exciting and versatile package.

Steadier and less lairy than the new, stumpy 1050 and for many that’s a good thing. The 955 Triple is a big, butch ‘mans’ machine yet with a big enough nod towards sports (decent brakes, suspension etc) to make it fun. Don’t expect to hold onto the shirttails of the latest supersports bikes and you’ll have fun – and have a more comfortable ride, too…

The second generation Triumph Speed Triple is one of the best. There’s nothing on earth quite like the fruity and fast second generation Triumph triple. As you might hope, this layout is a happy compromise between the easy, flexible torque of a twin and the free revving power of a four. In sportsbike mode the Triumph Speed Triple has always been a little lacking somehow, but as a streetfighter it’s an absolute blast bettered only by the superceding 2005 1050 version.

Hinckley Trumpets are reknown on the whole for being pretty solid but there has been the odd glitch. Thankfully, most owners tend to be pretty scrupulous about dealer servicing and the factory has corrected any faults. Triumphs tend to get cosseted, too, but look out for usual wear and tear…

If you like the style, you’ll love the Triumph Speed Triple. Engine, handling, practicality and fun factor are all up there with the best, which explains the Triple’s continuing popularity. On the downside, that keeps prices somewhat high, but the Triumph Speed Triple is still good value. Find a Triumph Speed Triple 955i for sale

The Triumph Speed Triple can be fairly flash – if you stump up for the extras. In stock trim it’s pretty basic, only when owners have lavished their motorcycles – Harley-style – with goodies from the Triumph catalogue does the Triumph Speed Triple start to glitter. Look out for factory flyscreens, belly pans, huggers, noisy cans and assorted carbon or chrome cosmetic nick-knacks, they’re worth the extra…

5 out of 5 2004 Speed triple 955i
10 September 2021 by Cvrle

Year: 2004

Bike is easy to drive, as soon as you accept hard gear change and weak rear brake. Torque is nice in all gears above 2000 rpm, front brake is good.

Ride quality & brakes 4 out of 5

Good ride quality. Front brake is 4/5 and rear one is 2/5. You can feel front brake anytime and stops nice. Rear brake is weak, cant even block rear wheel, but it can help a bit in stopping. This one have Wilbers 641 shock at the back and K-tech parts inside front suspension and ride quality is nice, even two up. Good for commute, dont like city centre due to low speed and engine can go to 103 celsius when fan kick on, other than that nice bike to go to work or have a weekend ride. Wind protection is better then on my ex Thruxton but not near perfect. I am 188 cm, 93 kg and this bike is comfortable for me, I can ride it for 2 hours without pain. Seat can be a bit softer, but I like it this way. Engine is a bit oldschool, rough, big, but I like it that way. You dont have any electronical help like on these days bikes, but it is more fun. S3 have some weight, but when you get used to it you can drive it easy and fast.

Engine 5 out of 5

120 HP and 100 Nm doesn't sound too much on paper, but on real road it is more than enough. Yesterday new BMW GSA1250 wanted to have a contest with my S3 at stop light, and didn't have a chance (I didn't come too close to redline in any gear). My S3 have arrow slip-on and new map made according to that, throttle is smooth even at low speeds, and delivery is nice, no jerking at all. When cold, give it 2-3 minutes to warm up at sidestand.

Reliability & build quality 4 out of 5

I have the bike for 2 months now, and it is in good shape except one small oil leak at right front side head gasket. Hard to notice, and still not sure is it about gasket. Engine pulls strong and no problems at all.

Value vs rivals 4 out of 5

I can do regular small service by myself, other than that I go to shop. Bike hold its value good.

Equipment 3 out of 5

not equiped at all :) but ex owner did some changes ... I have USB 2xsocket next to speedometer, and I have extra cable to maintain the battery. What else do I need?

Buying experience: 2 months ago I bought this bike from older guy who have 7 more motorcycles. He had all documents and bills, and he took a good care for S3. Price was 3800 € with 36000 km, all history, new suspension, 2020 dunlop tyres, oil change, and engine chain change at 33000 km, mint condition.

Likes - styling, engine, brakes, fuel economy Dislikes - comfort, weight

Ride quality & brakes 4 out of 5

Strong front brake, not much at the rear. Ride is reasonably compliant, at least compared to the gsxr1000 I had before. I do still find it quite uncomfortable though. Leg room is tight for me at 6' 2".

Engine 5 out of 5

Engine is quick enough. Nice and smooth between 2500 rpm and 4000 rpm, gets a bit vibey above that but also really starts to pull.

Reliability & build quality 5 out of 5

It seems very well built, especially being 16 years old. I've owned it for 18 months with no issues. There is very little corrosion anywhere on the bike.

Value vs rivals 5 out of 5

I serviced it myself which probably cost about £80 for oil and filter, air filter, fuel filter and spark plugs. Not sure on the dealer cost. I am impressed at the fuel economy. Averaging between 55 and 60 mpg riding on country roads at 60 mph with plenty of overtakes.

Equipment 3 out of 5

2004 bike so not much equipment above the bare essentials.

Buying experience: Bought privately for 2900 in 2019. The bike had 19000 miles on the clock but looked pristine and very well cared for.

Had mine a couple of years, so good it's been nicked twice. I'm tall and find it comfy enough to blat about all day. No strain on my poor old back. Won't keep up with pocket rockets but growls when she needs to. Looks pukka, plenty of comments if you like that sort of thing. She overheats quick in traffic and the fan kicks in about 103. Check oil level frequently. Mirrors need to come off as they look ugly, and then you're good to go. Average 130 miles before fuel light comes on. 21 litre tank.

Ride quality & brakes 5 out of 5

All round fun. 4-hour ride to Devon? No pains or aches. Commute, fine, just keep moving to stop the overheating (like any sports).

Solid build. Thin coated Triumph paint. Had the starter/sprag clutch replaced @ 20K. Luck of the draw.

Value vs rivals 4 out of 5

New rubber only real costs. Spent about £600 to get valves done, but that's the same on any bike @ 24K

Equipment 4 out of 5

Shovel luggage rack for trips and some panniers if you wanna eat after work. No real space under the saddle apart from a disc lock or spanners to get to the battery (2003 version).

Buying experience: Dealer £3500 with about 18K and all the accessories on her. Belly pan, bikini fairing, rad guards and luggage rack. Not bad.

It looks incredible, especially in roulette green. Does everything bar off road nonsense. Commuting, track days and touring. No fancy electrics, traction control, etc. It's just you and the bike!!

Ride quality & brakes 4 out of 5

Rides well solo or loaded with luggage for overseas touring. 150 miles before fuel and leg stretch required. Brakes good.

Engine 5 out of 5

Power just right. Who needs 165 bhp?

Reliability & build quality 4 out of 5

Solid lump of (mostly) British metal and plastic. Wears well. Fork seals and speed sensor have been replaced. Corrosion minimal. Just keep it clean. Mine lives outside under a cover and doesn't get ridden in winter. Keep battery charged up or it will die !!

Value vs rivals 4 out of 5

40 - 50mpg. Uses no oil between services. Triumph dealers expensive for servicing...only use if you have to. Find a local mechanic.

Equipment 4 out of 5

Twin round headlights still look the part and the colour (only thing spoiling new Speed Triples is the lack of round headlights and a roulette green option). Fit heated grips and a Triumph high-level race pipe (if you can find one). Michelin 2CT tyres or Avons are recommended.

Buying experience: Bought from (very good) dealer in Suffolk 4 years ago. Paid £3500 I think. Very low mileage at the time...now approaching 25000.

Best feature is usable power coupled with easy riding style

Ride quality & brakes 4 out of 5

Ride is sportsbike firm so it does tend to crash through potholes. However a two up ride from UK to German border last year proved they can tour if you compromise on luggage.

Engine 5 out of 5

More lovely triple torque than I'll ever need.

Great looking and very eye catching bike. Good quality parts and exceptional paint quality. Enough power for most (120bhp) and enough torque to tow a caravan! Original can very heavy and best replaced with carbonfibre end can.

Very reliable but if any check lights come on it's best to get a dealer to cancel them to ensure no gremlin problems occur.

Only servicing I do is change the oil and filter every 3000 miles.

Had it just over a year ,it had less than 6000 miles on the clock and is an 04 i have put another 5000 miles on it in just over a year.only warped discs spoil the picture otherwise it has been spot on.fitted a fuel can plus the fly screen and a visor for from bullster in france,it has made a big difference and to my eye looks a lot better than the laminar version.My third triumph and i have loved them all.ny last being a sprint st that is now embedded in a fiat punto !only problem now is that it has turned me into a hooligan.oh well.

07 December 2009 by triumphross125

had my speed triple a year now and love it to bits, however the piston rings have gone with only 9000 miles on it, i bought the bike from a triumph dealer (two wheels in edinburgh) the problem with the rings started within my warranty period but i was basicly fobbed off leaving me with an expensive repair, The attitude of staff at this dealer was appauling. this has not put me off the bike though and it will be fixed for summer, AVOID TWO WHEELS IF YOU ARE IN SCOTLAND, THEY ARE A BUNCH OF COW BOYS!!!.

06 April 2006 by stuzero

Just picked up a used speed four, it was actually a trade down from an old zxr750 so as the speed is a modern bike, theres not much trade off top end, but the acceleration of the four blows the old kwak out the water. bikes got a lovely mid-range that just wants to pull all the way to the redline, but is just as good in 6th potterin round. it handles like a dream, you can just throw it down into anything because you know you can trust the chassis and the incredible stopping power of the brakes. look past the looks which you either love or you hate personally i think it looks so unique that you have to love it. It is truely an amazing package, take one out and give one a try I promise blast some b roads and you'll want to hand over the cash!!! Strengths: Chassis, brakes, engine. Weaknesses: Looks bit 'unique' for most middle of the road/fashion following people.

5 out of 5 Great allrounder, handles well with amazing looks
11 January 2006 by Ridethelightning

If its a 600 mid range bike you're after this should definately be one to look at. With very few around and radical looks (gotta love those air intakes!) and some unusual colours to choose from (get it in GREEN, it goes faster!) its guaranteed to turn heads. Although I haven't ridden many bikes but I know this one has amazing handling, it gives me that extra confidence going round corners and even though I've spun the wheel out a few times it always gets itself back upright with little effort. With so many speed cameras and the such on the roads these days it can handle any speeds your likely to ever go. It tops at 148 so unless you are going to do track days you dont need any more. The power is there so getting it up to the ton takes very little time, tho you really dont want to stay there too long as the small fairing becomes pretty much useless at anthing over 80-90mph. So far had no problems, apart from the Scottish weather. Strengths: Looks, handling, Noise (not like those Japanese hairdryers), so far no problems. Weaknesses: Little wind protection.

5 out of 5 The absolute nuts of a naked bike and very overlooked
03 January 2006 by Djpinhead

The Triumph is one of the best looking naked bikes on the road with very distinctive looks to set it apart from the rest. The engine has got a nice bit of power for when you want to be a bit of a hooligan but is let down by the fuel injection that is a bit notchy at low speeds but don't let that put you off because it is a very well made machine that anyone would love from experienced to novice, so make sure you take a look before deciding on something else as there are some good deals going. Strengths: Power, distinctive looks, good brakes, excellent build quality and a hell of a lot different from the rest of the naked bikes out there. Weaknesses: Fuel injection is notchy at low speeds and wind protection but what do you expect when you buy a naked bike.

22 June 2004 by lcjohnny

This is a little hooligan! Yet when the adrenalin has got too much and you are going too fast too late into the corner...those excellent brakes and the exquisite handling pull you out of trouble every time. It is civilised when you need it but a twist of the wrist has the needle bounding towards 13k with a beautiful induction yowl. This is the four stroke LC reborn! Strengths: Handling, eager engine, brakes, style, handling & brakes. Weaknesses: Poor wind protection above 90. poor gearchange below 4,000.
