Performance With
A Sharper Edge
85 SX Powerplant
The compact 85 cc engine uses a 6-speed transmission and powervalve to tailor strong, rideable power across the rev range.
6-Speed Transmission
The lightweight 6-speed transmission matches the engine for quick shifts, while no-dirt features help maintain reliable operation.
38mm Mikuni TMX
The 38 mm Mikuni TMX carburettor delivers smooth, controllable power and stays less sensitive to altitude and temperature changes.
Hydraulic Clutch
The FORMULA hydraulic clutch keeps lever effort light and bite point consistent across changing track conditions.
Balanced Crankshaft
Optimised crankshaft balance reduces vibration while retaining torque, revs and easy rideability.
Compact Crankcases
High-pressure die-cast crankcases save weight and place the shafts close to the centre of gravity for better handling.
CFD Cooling System
CFD-optimised cooling keeps engine temperature stable, while low-mounted radiators and protectors support handling and durability.
Smooth Shifting
A coated shift drum makes gear changes smoother and more reliable over long hours of track use.
TECHNOLOGY THAT CONNECTS
RESPONSE AND CONTROL IN SYNC
Adjustable WP Suspension
Adjustable WP XACT fork and monoshock settings adapt to rider weight, preferences and track conditions for better control.
Sharp by Design
Agile by Nature
Radial Brakes
Formula radial calipers and lightweight wave discs provide controlled, powerful braking with clear rider feel.
Chrome-Moly Frame
The hydroformed chrome-moly frame uses robot-welded tubes for consistent flex, strength and precise handling.
Race Graphics
White, orange, black and purple graphics give the 85 SX a distinctive race-ready appearance.
Aluminium Subframe
The lightweight aluminium subframe supports the rear fender while adding rigidity and handling stability.
