Yamaha's YZF1000R is one of today's best supersports bikes, but it is up against some tough competition. The FireBlade has a huge following, and the Ace has never come close to stealing the Honda's thunder. The YZF1000R even plays second fiddle in the performance stakes to Yamaha's own R1.
So why would anyone want a Thunderace? It's all about horses for courses. If you want one of the most focussed 1000cc supersports, then the YZF-R1 is for you. But the R1 is too extreme for most riders who have to get to work on a wet and windy Monday morning after their trackday thrash. If you want a bike that's a brilliant all-rounder the Ace is a better buy.
Heart of the Thunderace is Yamaha's legendary 1002cc 20-valve forward-slanting liquid-cooled four-cylinder motor. It is equipped with downdraught carburettors, throttle position sensor, gear position sensor, and a torque-boosting EXUP system for massive low- to mid-range performance.
With a claimed 145bhp at 10,000rpm there's plenty of grunt available for easy roll-on overtaking. Keep the engine spinning above 7000 and this bike really motors. Top speed is a touch over 160mph.
Like its little brother the Thundercat, the Ace has a 'an aerodynamically-efficient fairing and low stress ergonomically-developed riding position'. Which means the Ace is a lot more comfortable to ride if you want to cover long distances quickly. The Thunderace handles pretty good too, thanks to the super-stiff alloy Deltabox chassis.
The 298mm front discs and lightweight four-pot calipers are some of the best available on a street bike, and are the same as used on the 175mph R1 - in fact, the Thunderace was running them two years before the R1 was launched. The superbly engineered one-piece front brake calipers deliver enormous stopping power combined with bags of feel.
Think more sports-tourer than supersports. Fast, comfortable and with sure handling, the Thunderace is a great all-rounder.
