Hey I have resently had a Yamaha PW 80 and it was great. I am kind of sad that I had to sell it because of my grades and I love it. This is a really nice riding bike because I have really taken this bike on some hard to ride places down the powerlines and on the road and I only had one problem and it was the chain because it sometimes was not all the way tight. This bike will really handle some hard things because I would ride it through rivers and jump hills and go about 60 mph down the road it was the funnest thing in the summer. It would go about 10 miles on a full tank. I would ride all day with my friends and come bike the next day with about 2 1/2 miles left. It goes pritty fast but not as fast as I wanted it to. I wanted to put some reeds in it so it will go about 10 to 20 mph faster. Some kids don't like to fast but ima speed demond. So if you have a child that is 10 to 12 then this should be for them. The brand new price is $799.95 but I got mine for cheaper and it was about $549.99 and it ran great. If you get one you will have to get used to it and when you ride it for a while it will go a little faster. The Yamaha I had was fuel injected and that means you have to get a type of oil that you put in a seperate tank that it get injected the gas and mixes around in it to make the right fuel you need and if you don't want to have it fuel injected then you should get a 4 stroke. Hope that this review will help you in any way .
