***Production heads will have a DRT logo engraved on them***

DRT cylinder heads are the cutting edge of cylinder head design, offering optimized performance for every riding style. Proudly designed and manufactured in the United States!

Benefits compared to stock:

-Optimized performance: more power where you need it, when you need it

-Choose between 3 dome insert options. Order one, two, or all 3 to unlock full control over the feel of your engine. Each dome offers very different power delivery characteristics!

-Increased detonation resistance: more efficient combustion gains performance while also increasing reliability

-Better cooling: targeted heat removal where it’s most needed, giving further reliability gains

-Cleaner, more consistent jetting

-Reduced fuel consumption

Domes A through C are safe to run on 91+ octane (AKI) pump fuel. While each dome varies in  compression ratio, they each have chamber geometry optimized for specific power delivery profiles. Please refer to the descriptions below to decide what will best suit you and your riding!

Dome A (low compression): Mellow but very luggable low end with a linear feeling transition into a free-revving top end. The most friendly to ride but not lacking in torque or response. Great for beginner riders but plenty of fun for experienced riders too! Offers great control of traction in slick conditions.

Dome B (mid compression): Luggable low end with a quick ramp into strong top end pull. Slight torque increase with quicker revving and harder hitting power band compared to dome A. Classic “250 2 stroke” feel! For the rider that likes some spice when they get on the pipe!

Dome C (high compression): Hard hitting and luggable low end with a broad mid range. Offers the most low end torque and peak power. Snappy and "connected with throttle" feeling power . Yeah, this one pulls hard!
