Why Our Engines?
IMG-4955 (1).jpg

Experience the difference with our premium kits, packed with features our competitors simply don't offer:

 

WILDCAT Trued, Full-Size One-Piece Crank

Our engines are nearly a pound heavier due to the full-size flywheel and trued crank, ensuring better performance and durability. Unlike other sellers who shrink the size of their flywheels to cut costs, we prioritize quality over saving a few bucks. As of 2024, we are the only seller who still has full-size flywheels!

 

Old Style 415H Chain - Thicker, Higher Quality, Stronger

We use a robust chain from a long-standing and respected factory in China, ensuring strength and reliability. Other sellers use budget manufacters of chains that only produce 415 chains (lacking the "H" standing for "heavy". 415 chains are not reliable for motorized bicycles, commonly breaking at the links. Our 415H chain is very reliable.

 

G4 Cylinder with Open Transfer Ports

Our engine kits come with G4 cylinders featuring open transfer ports, ensuring superior performance. While some competitors offer this cylinder, they lack our other critical upgrades. Avoid outdated cylinders with small transfer ports found in most low-cost kits.

 

4-Bolt Chain Tensioner - Thicker and More Secure

Our 4-bolt chain tensioner is now widely copied but never matched. We use thicker, higher-quality materials to make our bracket, ensuring a secure and durable installation that outperforms flimsy alternatives.

 

Motorcycle Style Throttle Cable from a Respected Factory

Our throttle cables, sourced from a trusted manufacturer, feature stronger strands, making them less likely to break and more reliable over time.

 

Thicker Hardware for Mounting Bolts - Grade 8 (8mm vs. 6mm)

We use 8mm Grade 8 bolts for mounting, unlike the 6mm bolts used in most low-cost engines. These thicker bolts withstand engine torque and vibration, significantly reducing the risk of snapping.

THE MOST IMPORTANT PART OF ANY ENGINE IS THE CRANKSHAFT!

Our competitors engines have a un-trued, 3 piece crank with poor quality bearings and bolted on weights.

 

Our crank shown on the right is a one piece, factory balanced crank with smooth, long lasting Japanese branded bearings and is a feature of Wildcat 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 trued 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 California Motorbikes 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 Wildcat has wide open ports.

Wildcat 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 Wildcat 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 Wildcat motors. 

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