I have a gx390 open motor with 38 hp and a tkm 125cc I am looking to buy a chassis ,I was told a ultramax excentrik. But is that a good choice ? can I get some suggestions?
Twister. Love mine. Been told charger too. However if I could get my hands on an Olson, you'd have to pry it from my cold, dead fingers!! Lol.
Olson is purpose built for big power and weight. Pretty much developed for the open outlaw world. Lol. I've never ridden one but I've talked with Greg a couple times and been doing my research. Its not a ''stocker'' chassis.
