2020 NEW FEATURES
ENGINE
4-stroke RR-S (350/390/430/500 cc):
• A complete redesign, with the aim of reducing the weight and bulk of moving
parts, achieved by raising the clutch and moving the crankshaft back. Moving the
center of gravity closer to the swingarm pivot makes for significantly better han-
dling. An overall weight reduction of 2.2 lbs.
• A redesigned magnesium clutch cover, redeveloped to improve the oil flow into
the clutch assembly more efficiently.
• Magnesium flywheel cover, redesignedin-line with the rest of the engine, now
with a more functional and modern look.
• New water pump system that improves flow-rate and therefore the efficiency of
the cooling system’s ability to transfer heat, keeping average temperatures lower,
improving performance, and providing a more simplified cooling hose system.
• Cylinder and head redesigned matched with the updated cooling system to
lower engine temperatures.
• Twin Injectors improve performance and increase fuel mileage.
• Oil circuit redesigned to provide better heat transfer between oil and water in
the front section of the crankcase in order to keep the oil temperature lower.
• Clutch with redesigned discs in a new material to ensure smoother and more
modular gear shifting.
• Redesigned gearing, now shorter and lighter.
• New gearshift mechanism with lighter cam to improve shifting.
• Gearshift lever redesigned in line with the new engine and frame layout.
• Addition of a neutral sensor.
• Updated EFI mapping.
2020 Beta RR-S (Street Legal Off Road)
2-stroke (250/300 cc):
• Now with a counter-balancer to reduce vibration by increasing inertia and im-
proving the power delivery curve. The counter-balancer improves the power deliv-
ery throughout the rpm range.
• Cylinder head redesigned (250 cc only) to improve torque at low rpm.
