What is the best UDP out there. ANy revews would be appreciative.

 

I have definitive udp and very satified with it. Bought it on a group deal a while back. So far no problems with crank sensor, perfect fit. At first you'll feel the car accelerates alot easier after a while you dont feel the power gain anymore. Shouldve got a y pipe first but overall good mod.

 

I haven't had any problems with my motostorm udp. good product.

OK, I'm deciding on dfinative and motostorm. The motostorm one is cheaper, but it doesn't seem to be in stock. Do either of these companies send the belts with it? Oh, and does the car have a shaking after this mod?

 

Yes when i bought my definitive they sent me belts.

 

most of the responses are gonna opinionated since most people only buy and install 1 brand UDP. Ive had no probs w/ mine (motostorm), only good things to say about it. Only one ive bad stuff bout is RVM.......
