Just finished installing the new CVTech Trail bloc Primary in my 15 XMR 800R. Clutch was tuned by Kevin @ Get-Torqued. Pretty straight forward install, I’m currently using the stock secondary spring but a replacement is coming from Kevin shortly. I’m also using a Gates C12 belt as per Kevin’s recommendation.

In very short summary this is what you can expect over a bone stock XMR Primary Clutch.
1. Butter Smooth engagement, no jerking, 2100rpm engagement and you can take off in a civilized manor.

2. In High Gear I’m pulling 7350-7550 rpm from a 5MPH roll. The bike actually pulls the front tires off the ground easily in high gear now, where it never used to at all.

3. Low Gear I need to do testing to check the RPM still. I can tell you though the motor is singing nicely along. Stabbing the throttle here will put the bike on the rear bumper lol, oh did I mention wheelies are fun? Peak RPM should be a couple hundred higher then high gear.

4. The only downfall is that a blip of the throttle is needed between gear changes at times, this was noted by several other members as well.
