Welcome goka! Did you make the Joyners? Looks like they are toast (out of business). Get your parts while you can Joyner owners    Do you have interchangeable parts for them?

The price is very good on some of the Chinese machines and the list of standard features is impressive. Everyone concerned about overall quality (including quality of accessories), weight, performance, parts availability and wether or not the company will be in business next year. If a Chinese co. would step up and compete with the Japanese (and American - don't forget Polaris - they own the Sport market) comanies it would be good for everyone.

I really like the styling of the KLUNG 500cc 4x4/2x4 - very cool. 590cc might be a little under powered, but it would be cool to see what it can do. The other machines look big/heavy. Have Klung send you to the Rally On The Rocks:

We can run some of the toughest/funnest trails in the world with enthusiasts and see how the Klung machines perform  No better exposure than that. Bet they would be happy to sign you up as a sponsor too. You could demo machines and get real feedback. This is how the Japanese and American companies do it.
