I have had the Rekluse Pro on my 06 YZ450 for about 2 months now. I don't think I will ever go without one again:prof: I installed it during a top end rebuild and I also added a Dr D full pipe too. I had to adjust my jetting to get it perfect with the new pipe or the bike would stall. Once jetted correctly though it was perfect. It engages just above idle and I still get full engine braking. You only free wheel the rear if you have locked it up from the brake. You then have to blip the throttle to engage it again. I also switched to the left hand brake with the clutch override. I am still getting used to it, but it has some huge advantages over a foot operated one. The fact you can throw your right leg out in right hand turns is big, but coming down big hills I also found its easier. It also helps to have it as if you have to bail off a hill on the left side of the bike you can grab the rear brake. Since the clutch will disengage and the bike will just idle it will also free wheel. Last thing you want is to see your bike idling back down the hill without you:naughty: I have also been riding for about 15 years and I can say riding can actually get better:thumbsup: I just ordered another for my new KTM 530EXC-R:ride: I also got one for my wifes TTR125!
