SuperBusa blasts past 218mph! Road-legal TTS Performance SuperBusa takes straightline speed to the next level

MCN’s resident speed tester Bruce Dunn has taken the British-built TTS Performance SuperBusa to an astounding 218.1mph in an exclusive test at RAF Cottesmore.

The supercharged road bike is available to anyone brave enough, for around £50,000, and is based on the current Suzuki Hayabusa. Built in celebration of the Silverstone-based speed demons’ 40 years in business, it’s currently limited to a run of just 40 bikes.

“This is something else,” Bruce said after completing his final blast along the runway. “To be fair, it’s more usable [than other bikes]. We also had a Kawasaki Z H2 here this morning and that feels a bit more vicious and a bit more abrupt.

“This is addictive. The way this makes power – you’ve got to be careful,” he continued with a smile. “Obviously I’m quite focused about what we’re doing, and the speed range you’re operating in means you’ve got to keep an eye out for other things.

“The speed really comes to your attention when you come out of the bubble, shut off and the windblast hits you at nearly 220mph.”

MCN first tested the SuperBusa in 2022, when it achieved a 9.69s quarter-mile time at 164.25mph before going on to a top speed of 194.23mph. Back then, it was in drag racing mode on standard Suzuki gearing and produced 370.9bhp at 10,752rpm.

Still pulling hard at the rev limiter, TTS made some revisions ahead of this second meeting – adding one tooth to the front sprocket, to bring it to 19, and taking two off the back, bringing it down to 41. They also performed some laptop wizardry to bring the power up to a dyno-recorded 401.14bhp at 11,191rpm – all in a bike that weighs 257kg ready to ride.

“At that speed, there was a low frequency weave,” Dunn continued. “It wasn’t a problem, you’re just aware of it. To get it to go faster, I think if we had a bit less wind then it would probably stabilise itself. I’d personally just put on another front sprocket with another tooth.

“It’s supercharged, super-fast, and you can use it to ride to the shops! In this day and age, I celebrate this stuff.”

TTS are currently building a SuperBusa for a customer in the UK, with two further bikes destined for customers in the USA. Motorcycle import laws in the country mean the finished machine cannot be shipped as a whole package, though, so they will be assembled and fettled upon arrival.

Alongside the monster performance, which starts as 370bhp and 190lb.ft when you buy one, you also get an arresting new single-sided swingarm, aftermarket Rotobox Bullet carbon-fibre wheels, plus carbon-fibre winglets, intercooler tank vents and drive cover. It runs 330mm StopTech front discs, a TTS rear disc, re-valved front suspension, and titanium fasteners.

If your wallet stretches far enough, you can also have a Brembo rear brake caliper and master cylinder upgrades. They’ll also bolt in an Öhlins rear shock, add rearsets, and give you a choice of 10 paintjobs – or something bespoke from Kardesign Koncepts, who penned the look of the bike.

Following the top speed runs, MCN also caught up with TTS owner and CEO Richard Albans, who said he had to “climb down from the ceiling” with excitement, after hearing the results.

“With the gear ratios and rev limit, I calculated it would do 218mph and we did just that,” he said. “I don’t think we could go faster than that.

“It felt faster yesterday with the higher gearing than with the standard gearing. It was more alive across the board than when we last rode it in anger. It even felt a lot sharper off the line.”

High-octane Hayabusa: TTS supercharger delivers at least 300bhp at the back wheel on road-legal Suzuki

First published 29 April 2022 by Jordan Gibbons

Silverstone-based TTS have created a bolt-on supercharger to fit every generation of Hayabusa and it catapults the horsepower at the Suzuki’s rear wheel to between 300bhp and 360bhp.

The kit uses a new design of anticlockwise supercharger from Rotrex, which has allowed TTS to simplify their original set up and so reduce costs both in manufacturing and in the install. The result is a kit that helps a bike charge smoothly to the redline with no lag, from £4560.

What’s more astonishing is that very little modification is needed to the stock bike. The only engine mod needed is a thicker gasket to lower the compression. Elsewhere, the injectors require a small tweak and an uprated fuel pump is fitted.

The ECU needs remapping, with TTS supplying three base settings, these are – A: Progressive power in lower gears; B: Full power in all gears; and C: Limited power.

While most supercharged bikes will be heading straight for the drag strip, it does mean that by tailoring the power as and when you need it, a TTS-kitted Busa can make for a perfectly usable (and legal) road bike – although TTS do recommend a longer swingarm for road bikes because that 300bhp+ does tend to send the front wheel skywards under acceleration.

In keeping with this desire to keep any modded bikes usable, the supercharger kit has been specifically designed to not reduce ground clearance on any of the three generations of Busa, while the supercharger belt is protected from debris by a machined guard.

TTS have even gone to the effort of building a custom intercooler hidden under the petrol tank cover; this is force-fed air by the fairing vents, so the bike looks as factory original as possible. Other than the supercharger itself, the only other giveaway is the oil reservoir for the supercharger and oil level indicator, which pokes out from a vent in the fairing.

So just how fast is it and how powerful is it? For Gen 1 models (1999-2008) the kit gives the bike 300bhp at the rear wheel, while for Gen 2 (2008-2018) and Gen 3 (2021 onwards) it is 360bhp. Torque, meanwhile, is boosted to 190lb.ft on all variants.

To give an idea of speed, TTS’s Gen 2 development bike (which packs 400bhp at the rear wheel) managed a quarter-mile time of 9.1s @ 161mph. Quite quick, then.

Costs vary from model to model but start from £4560 for the Gen 2 kit, with a lead time of eight weeks because each is built to order.
