THE MOST IMPORTANT PART OF ANY ENGINE IS THE CRANKSHAFT!

Our competitor's engine has a unbalanced, 3 piece crank  with open, unsealed bearings and bolted on weights.

 Our crank shown on the right is a one piece, factory balanced 40mm crank with sealed Japanese bearings and is a feature of HELIO motors.

 So, what's the difference?

 The 3 piece crank starts to vibrate unbearably at 20mph, to a point where your hands hurt from the punishment of having to hold on to your  handlebars.

 Our one piece cranks, however, maintain low vibration at screaming fast speeds!

Our competitors use the cheapest bolts they can get in order to cut costs where possible. 

​At Heliobikes.com we find that the quality of the bolts is very important so we use grade 8 hardened bolts on our engines. 

​Our engine mounting bolts are thicker in diameter and stronger.

Our engines come stock with the speed carburator, which features larger fuel jets for more power

Small ports restrict flow and take away from power, fuel efficiency, and top RPM. The HELIO has wide open ports.

HELIO features a 4-bolt chain tensioner that offers more reliability and a stronger grip on your bike frame. Two bolt tensioners struggle to grip to the bike frame.

Our chain is hardened, not standard! 

Another cost-cutting, corner-cutting feature of our competitor's kits.

Rattlecan finish? Really?

​You won't find that on HELIO engines!

We use a high quality fuel and heat resistant paint which is baked on at high temperatures.

Higher quality, higher flow fuel filter comes standard with HELIO motors.

Slightly smaller sprocket with HELIO motors gives you a higher top end speed.

HELIO Engine Kit: $144
