Engine:liquid-cooled 2-stroke; reed-valve inducted
I called up and got this and a couple of other bikes to test. When it got here, I was a little worried about the performance end. I fired it up and was taking it easy, I took a couple small doubles set up off a table top and got a little too much in the power band. Needless to say, I had a sore rear but when I got back on and rode it around, this thing is all about business. Not saying anything bad about fours but man if you sell yourself short coming up on the face, this thing will set you back in the slot in no time. It has more power then anything I have ever been on. Now that the break in is almost over, it’s getting smoother all the time.
Yamaha, with this great bike, managed to built one of the baddest two strokes in the market. I couldn’t believe the craziness of this bike. It’s a power monster. It’s definitely one bad ass mean machine. I have enjoyed every second of it. It is a great bike even in stock form. It handles great, very fast, and is easy to work on. Very easy to upgrade with after market parts. This bike loves to fly and handles turns like it is on rails.
Yamaha has done a swell job on this machine. . If you are a two stroke fan, it’s the bike to go with. I love it. Nice job Yamaha. Nice job!!!!
