I have ridden a WR since 1998 (a new one almost every year) and love them, but for some reason I bought an 06 YZ450. Great bike with tons of power, but I can't stand how the gearing is so high (I do a ton of very technical, single track bush riding), and it will stall at low rpms even when you work over the clutch. I bought a 53 tooth rear sprocket, but still find the gearing is not what I like. I was looking to get some fly wheel weights to help the stalling, but then saw the Rekluse clutch. I have seen them before, but never looked further into them. Can anyone give me some feed back on how they feel? I am kind of worried it will feel like my sons KTM 50, and be real jerky when it engauges. I was also wondering about the pro vs the starter. What is the main difference. I have read the web site, but as I say hoping someone has real world experience with them. Thanks.
