Bringing Panterra 125 back to life - piston size?

[mot]

Hello Everyone,

Forgive me if this is a repost. I could not find evidence that my previous post went through.

Im bringing a Panterra 125 back to life after it has not been touched in 10 years. It is like new, but had water in the cylinder. I bought the bike probably in about 2005.

I would like to verify the piston/cylinder size before buying anything. Can anyone verify who made the engine for for this bike and the bore size? I see a lot of piston kits available for 125's but it seems the bore sizes are slightly different. I think I can salvage the cylinder, but want to get the correct piston.

More generally, does any know of source of technical info for this bike? Parts diagram etc. Also any special forum dedicated to the Panterra 125?

Thanks- Mot
