Im not sticking up for trinity by an means, but i have a couple of close buds that run cheetah pv motors! 400pv,485pv,and a 492pv, and soon to be a 535pv! I have ridden all 3 bikes and they are all incredible!! Very smooth power and VERY forgiving! The 3 guys that ride these bikes show no mercy at them and the motors take whatever they throw at them!! Now granted they are older motors, probably purchased in the mid 2000's... But all are very impressive!!
