I had an early 250 x-lite. It had some issues mostly related to the starting system. That being said, they did improve over time, and were much better after ditching the Mikuni EFI. The electric starter just never seemed to get better, though. The motor is nice inside and very easy to work on, although a good torque wrench is recommended unless you want to become a helicoil expert. I would only hope that GasGas would further refine the system before just shoving it in a GasGas frame. I look forward to hearing about what they've done or not done to that engine since they bought the technology. There were also rumors of an X-lite 450 under development - I wonder what happened to that (if it ever existed in the first place)?
