The engine is also equipped with an oil cooler. A pair of Mikuni 38mm carburetors feed the engine. The clutch is a hydraulic master-cylinder clutch with separate tanks. The six-speed gearbox is pleasant and precise, although sometimes shifts are missed between 5th and 6th gear. Maximum speed is a little over 120 mph.
Power delivery is very linear while the torque spread is relatively flat.
While the engine hasn't changed, the M900S weighs less than the standard Monster. With the liberal use of carbon fiber parts its claimed dry weight is down to 403 lbs from 407 lbs. The most significant improvement the Monster Special offers is a brand new, fully adjustable 41mm Showa front fork and a single Sachs-Boge shock with spring preload and rebound damping adjustment. The stock settings are a bit mushy. Wheelbase and seat height remains identical throughout the entire Monster family.
