i run a 55t motor w stock gearing and i love it,,, goes up anything i want depending on traction,,, muddy hill climbs not so good, but rocks, dirt, water trail runs, 55t stock gearing perfect for me,,,
A good 35t motor will be able to do everything most 55t motors will do in terms of a Wraith, with the added bonus of some extra wheel speed. A 35t motor is as slow as I ever recommend to someone.
