Changes for 2020

Cylinders

• Precision honing of cylinder bores offering consistent sealing of piston rings at high temperatures.

• Faster and better break-in, resulting in both improved oil retention and longer cylinder life.

Cylinder heads

• Significantly increased cooling fin surface area giving improved cooling efficiency.

• Exhaust port reduced in length to decrease cylinder head temperatures.

• Optimised intake and exhaust port geometry improving inlet and exhaust gas flow.

• Redesigned cylinder head covers making maintenance easier.

Fuel injection system

• All new EFI system using Keihin throttle bodies.

• Electronic idle-speed control improving starting and stablilising idle RPM.

• Throttle position sensor added giving crisper throttle response.

• Fuel injector location optimised increasing efficiency.

• Closed-loop EFI system giving better

• fuel-efficiency.

• Fuel pressure increased improving fuel atomisation.

• New self-priming, in-tank fuel pump with integrated filter and pressure relief valve fitted.

• High-efficiency catalysts reducing emissions without sacrificing power.
