Not only Powerful, But also Flexible Control

Newly designed air intake system, dive-type intake duct, compression ratio as high as 13.9, improved combustion, strong high-speed power while taking into account low-speed torque.

Equipped with Bosch EFI and dual fuel injector system, it delivers smoother and more controllable power output.

Finger-shaped DLC rocker arm structure, titanium alloy valve + elliptical valve spring, speed up to 14000r/min, lightweight valve structure, cylinder eccentric technology, reduce power loss, longer life, strong power.

Lightweight two-ring piston forged piston, multi-curved irregular piston top combustion chamber, piston multi-point injection forced back cooling technology, DLC coated piston pin, and various technologies to lightweight the piston structure, thereby reducing the piston reciprocating inertia and improving power response.

All parts are lightweight, the power-to-weight ratio is as high as 1.14, and the power performance of the bike is improved.

Master Lightweight Design, Perfectly

We dedicated ourselves to a tiny pursuit:repeated testing, verification, revision and refinement,merely to cut off every single gram from the vehicle.The accumulation of countless grams brings the dry weight down to 102kg.It is never just about being light,but being lightweight yet tough enough.

All Designed for Racing

Both front and rear suspension adopt top-grade KYB specifications with precise matching. It has passed 240 hours of continuous rigorous testing to ensure outstanding durability under intense racing conditions.

Equipped with 22mm triple clamp offset design, balancing agile steering and front wheel stability.

It supports practical functions including power mode adjustment, launch control, quick shift and lap time recording.
