With this engine we take a new 150cc internal reverse GY6 engine, completely strip it down, bore out the case and rebuild the engine from the ground up with the 62 mm 175cc big bore piston/cylinder kit and any other performance parts that you desire.
Is this you rolling back down the hill?
Get the power you need!
The clip above shows hill climbing ability of our flagship 184cc GY6 engine (stroked, big bore, and high compression). (This is NOT the same engine being sold in this listing) The purpose of this comparison is to showcase our ability to radically (and reliably) improve the performance of the GY6 engine. The 175cc will make it up this same hill, unlike the 150cc.

Large valves for higher top-end powerArrives with Large Valves Installed
The large 27mm/24mm valves allow the engine to breathe better at high RPM, allowing for higher top speeds. This is a very noticeable improvement if your original engine came with the smaller 24/23 valves.
8-pole charging upgradeAlso includes STAGE 1 Electrical Upgrade
This engine comes from the factory with our S1 Electrical package, which generates more electrical power for lighting and charging the battery more rapidly.
