My neighbor has a Scrambler 500 and he just got his kid a Scrambler 90 two days ago. The 500 is a four stroke and it's got lots of power. The 90 is a 2 stroke and it seems pretty peppy too. It may even beat my sons TRX90? Not sure yet, he still has the throttle limiter on it until he's totally used to it. Anyway, I was wondering if someone could give me some links for some good Polaris sites and maybe some shops that specialize in Polaris hop ups. Thanks alot guys!
