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.”
