I've owned a Pitster X2R 140, an SSR0R, and now have the Motovert Pro YX150. The Motovert is the best bike of them all.
The fit and finish is awesome as well as their customer service. I am rough on bikes and this one has taken quite a beating so far. It has all the best stuff you can get for a China bike on it from the factory (bars,controls,throttle,brakes,hubs,pegs,etc).
Tommy at TDK is the man when it comes to customer service and he backs his product 100% no questions asked. It does not get better than that.
I bought mine from
