Man id much rather get one of the original Russian rega/Reva? Motors these are based on. Highly regret not picking one up on eBay in the early 2000's when they were available and cheapo.
This one certainly looks like fun, but I'd be worried that, and it looks like...they just kept slapping mods on the same old Chinese grubee motor.
Built one once, and the manual clutch was the best feature. Couldn't imagine one without it.
For that price I'd pick up a Chinese ktm 50 motor
