![]() ![]() In 2015 Yamaha released the latest YZF-R1. It barely made 150 horsepower at the rear wheels. The 09-14 Yamaha YZF-R1 also lagged a little versus some of its competitors too, especially in the US market where their emissions regulations are tougher. It took Yamaha until 2015 to respond effectively as their 09-14 YZF-R1, although an amazing machine was lacking somewhat in terms of peak horsepower compared to BMW’s S1000RR. The S1000RR caught the big four sleeping…. While we’ve seen models from all of the big Japanese factories lead the horsepower hierarchy at least once in the last 20 years, it has been BMW and their S1000RR which was released back in 2010 and has led the pack in terms of peak horsepower and straight-line acceleration. Litre motorcycles have been chasing big numbers with each new generation of machine one-upping the last in terms of peak power. Like all motorcycles that we plan to test, the Yamaha YZF-R1 will have its acceleration measured from a standing start in 10 mph increments all the way to its maximum speed. The Yamaha YZF-R1 will be the first motorcycle that Motostatz will measure against the clock. Piped Gixxer’s are no longer a problem! -)Thanks for the great price and fast turn around, by far the best performance dollars I’ve spent on this bike so far.The 15-19 Yamaha YZF-R1 is the latest addition to Yamaha’s legendary R1 range, and no doubt the fastest motorcycle from the Hamamatsu factory to date. The on/off throttle problem was gone, engine braking is gone, the bike responds immediately to throttle input and the additional over rev was mind blowing, it pulls like a freight train all the way through to redline! I was pulling about 12,800 rpm through turn 9 when I was there last month, I had to change my gearing because the first session out this weekend I was hitting the rev limiter before I even bent it in. “Just got back from a couple of days at Road Atlanta and finally had a chance to test out the reflash you guys did for my 09 R1.
