Put it this way I never got beat by another 4 stroke w that motor easy 55 HP holeshot champ. Going from being the slowest 450 out the factory 4 bikes slower. To 2-3 bikes inhead everything else equally built. It's priced like that strictly for fast sale I have The engine build sheet here of 2200$ somewhere and when I was parting motor was always priced at 1500$ I just want shit gone . So I can hop into a newer saleen lay some stompings on some m5s hahaha
