The 2008 Yamaha YZF-R1 is unashamedly based on MotoGP technology. The YCC-T fly-by-wire throttle system along with the World’s first electronic variable-length intake funnel system and slipper-type back torque-limiting clutch all come from MotoGP testing. A short-stroke 998cc DOHC, 16-valve, liquid-cooled inline four-cylinder engine produces more tractable power than ever; the Yamaha Chip Control Throttle controls a 32-bit ECU fuel injection system for super-responsive, smooth, instantaneous power delivery and a two-piece ergonomically designed fuel tank carries fuel in the rear section, which helps centraise the mass, while the front half contains a Ram-Air-fed airbox for increased power. God, this sounds like the spec sheet, but Yamaha have gone all out this year, perhaps with the knowledge that they will have to pull something spectacular out of the bag in 2008 to beat the Ducati V-twin 1198cc 1098 S since the introduction of an increased capacity for the twins in World Super Bikes. Yamaha have done their very best to increase aerodynamics, reduce engine friction and take advantage of the latest in computer control. Yamaha rider, Noriyuki Haga, came awfully close to taking the WSB championship last year finishing just 2 points behind James Toseland on the Honda CBR1000RR. Although it has to be said, Toseland rode the wheels off the Honda to win. It’s amazing what the chance of a MotoGp berth can do – Toseland is moving to Yamaha’s MotoGP squad in 2008.
Valentino Rossi and the YZF-R1
All in all, the Yamaha YZF-R1 is pretty much unchanged from 2007. Seeing the 2007 model came within a gnat’s whisker of winning the WSB championship, that’s understandable. Valentino Rossi, Yamaha’s MotoGp rider and several times World Champion took one for a spin and was very impressed.
Reviews and Opinions
Since it’s original launch, the Yamaha YZF-R1 has had journalists and reviewers reaching for the nearest superlative. Universally liked doesn’t even come close, in fact I don’t think I have ever had a bad word said about it. Yamaha really put a great package together with this bike. Race bred it may be, but as a road package it’s hard to beat. Impeccable manners, extremely powerful yet controllable engine, comfortable riding position. I know Rossi is paid to like the bike, but his comments actually seemed heart felt and I can’t imagine him laying down a line of bullshit just to sell a bike. At the end of the day, he’s more concerned with pleasing his legion of fans than sucking up to Yamaha.
I used to own the 750 version, the YZF 750RR and that was a joy to ride on a day-to-day basis. If you are looking for a usable, fast liter bike, this is a good bet.
