Think of your stock cylinder head like a plain cup of gas station coffee - it works, but it’s nothing special. A performance head is more like a turbocharged espresso shot. It brings more energy, efficiency, and style to your ride.

These upgraded heads increase compression, which boosts power output. They’re built with larger cooling fins and improved airflow to keep your engine running cooler and lasting longer. And, of course, they come in eye-catching designs and colors, so your build looks as good as it rides.

The UFO / AXE Cylinder Head is a top pick for riders who want quick and affordable performance. Compact in size, it maximizes compression while still delivering solid cooling. Its smaller profile makes it an easy fit for most builds, and the price makes it a great first upgrade for both beginners and experienced riders.

If the AXE Head is compact, the SHARK Cylinder Head is a beast. Designed taller with more surface area and deeper fins, it sheds heat quickly while delivering strong compression. Ideal for long rides, hot climates, or riders pushing their 2-stroke bicycle engine hard, this head keeps things cool under pressure.

It fits most 66/80cc engines, but because of its height, clearance can sometimes be an issue. Always check your frame fit before committing. If it clears, you’ll have a cooling monster that rips.

Looking for style and performance in one? The GT5 Cylinder Head balances strong compression with efficient cooling. Its smooth, rounded design gives your build a clean look while keeping performance consistent.

This head is a favorite for riders who want reliability without sacrificing looks. It runs smooth, stays cool, and fits beautifully with 66/80cc setups like the Zeda 80, Silver Slant, and Zeda Dio 80.

Here’s where things get next-level. The CNC Pro Dual Spark Plug Cylinder Head features two spark plugs, doubling the ignition spark for a cleaner, more complete burn every cycle. This helps reduce ‘4-stroking,’ improves throttle response, and provides smoother performance at higher speeds or under heavy loads. 4-stroking is when a 2-stroke engine fires inconsistently, often at low RPMs, causing choppy power.

It fits most 66/80cc engines including all of the Zeda 80 variants and comes with a matching dual spark plug CDI. If you’re chasing maximum power and the coolest spark setup on the block, this is the head for you.

If you're rocking the Zeda 100 Max Engine Kit, good news - we’ve got a CNC Pro Dual Spark Plug Head for 100cc too. It’s specifically designed for the larger combustion chamber of a 100cc engine, delivering the same elite benefits: higher compression, stronger cooling, and dual-plug combustion. Expect more torque, better throttle response, and improved stability across your ride.
