It claims to be an upgrade, but after I put it to the test on my motorcycle, I didn't notice any significant improvement in performance. The assembly looks flimsy and cheaply made and I doubt it would hold up to repeated use. While it may save you money compared to other automotive parts, in the end, you get what you pay for. Stick to well-known brands if you want your bike to last. Cons: cheaply made, lack of improvement in performance. Pros: affordable compared to other parts.See full review
