Engine
Continuing to utilise the latest 2-stroke technology, the TC 85 engine remains well ahead of its 85 cc competition by offering improved torque for 2025. A new cylinder head, spark plug, and ignition contributes to a 120 g weight saving over the previous generation while boosting overall performance. Two engine maps ensure the TC 85 performs in all conditions with a close ratio six-speed gearbox and hydraulic clutch completing the build of this highly competitive machine.

Cylinder
A light and durable aluminium cylinder is designed around an innovative powervalve system that ensures unrivalled performance. For 2025, a new cylinder head further improves bottom end to mid-range power, which reduces the need for riders to feather the clutch in heavy track conditions.

Crankcase
Manufactured using a high-pressure die-cast process, the crankcases feature thinner walls to reduce weight while retaining strength and durability. This design allows for a more compact engine arrangement that brings the internal components closer to the centre of gravity to enhance handling.

Clutch
The reliable, lightweight hydraulic system from Miba ensures consistent play, even in the toughest of conditions, and offers a near maintenance-free operation. The clutch itself is housed inside a strong steel clutch basket for consistent action and assured durability.
