Much better low end, and gives a huge RPM boost over the stock Hi-Torque on a Puch E50 Metrakit 65cc setup. Plus now all the fins line up perfectly on this kit!! Get one now.

This is a low compression head, look elsewhere

Either treats sent me a low compression head or this head’s performance is awful/more sluggish that stock. Take off is horrible and peak rpm’s where lower. My Tomos a55 engine responded very poorly to this head, put the stock head back on and it zipped to 44 mph like normal. The combustion chamber is 1-2mm deeper on this head with more squish. Stock compression ratio for an A55 is 10:1, so this head must be around 9:1 which is a little higher than a stock Puch 1hp head. Hey TREATS, the box says Puch 50cc head type II. If that’s wrong let’s get a return going

I bought this head for my stock e50 engine.I noticed an overall increase in performance, which was awesome! The downside is that it doesn't line up with the stock fins, so it looks a bit off.

Ran on a non-case matched vintage Athena 42mm/ZA combo. No over-heating issues. Good increase in low and top end over factory head. Worth the buy.
Huge improvement on a Metrakit 65cc!!
