Thanks, I ended by getting some GRO Extreme Gear 75W

New to trials, 2012 Sherco ST 250 (2T) I was advised to use GRO (Global Racing Oil) Gear Extreme 75W but not easy to get where I live. I run Castrol Active 4T 15W50 in my KTM 300 EXC gearbox be ideal if I could run the same. What are people here using? Cheers

If the problem is that it slips off the rim when the pressure goes down, the problem isn't a ...

Mine isn't the internal rubber band sealing type. The spokes attach to an external lip. Checked the valve stem and valve. each time I put it back together I submerse in water and can see the leak between the bead. It should be able to run tubeless at low pressure as it was designed to do.

Yeah, might be, but I put 80 plus psi and it went bang twice and on visual inspection it appears to be seated all the way round.

Hi all, I'm having a problem with my rear tyre. Despite taking it off numerous times, cleaning the rim and tyre I can't get it to seal around the bead. It pops onto the bead ok and doesn't leak when there is plenty of pressure but as soon as you let it down below 10 psi it leaks around the bead ...

I recently bought a 97 Techno. I had no luck finding any service specs on the net so I emailed Beta Racing. I've never dealt with them and they don't know me from a bar of soap but David there was kind enough to send me a photo copy of the tech data. I offered to pay but he said don't worry about it ...
