Clutch engagement

[Dirt-preacher]

Hello friends. I recently purchased a 2017 Evo 300 with low hours. I love the bike but would like better slippage on the clutch. It does slip but is mostly on/off engagement. I’m new to Trials bikes. Is there an adjustment for this?

Thanks for your help.

Good quality gear oil to suit a trials bike.

Moving the lever location on the bars so you are pulling further out on the lever.

Depending on how low low hours is 2017 is also old enough you might want to consider filing any ridges that exist in the clutch basket tabs from wear with the clutch plates.

Gear oil is crucial with the Beta clutch. When I had one I found that Putoline Nano-trans gave me the best clutch feel and progression.

The other replies are spot on, but the top hat washers on the springs on some beta models are also worth checking. They can be fitted either way up for more or less preload which makes a big difference to how the clutch feels. While you're in there there's a shim and a spec for the clearance at the end of the push rod, it's worth checking while you're on but it mainly affects drag.

Two very good points that I had forgotten.
