Engine

Producing a peak power of more than 63 hp, the SOHC, 450 cc engine is the result of advanced engineering techniques and tips the scales at just 26.8 kilograms. Mass-centralisation of the key components was key during the design process, as was repositioning the engine closer to the centre of gravity for improved handling and agility. This was achieved by tilting the engine 2 degrees backwards, which resulted in the countershaft sprocket being positioned 3 mm lower. The end result is significantly improved anti-squat behaviour from the chassis for smoother acceleration on rough terrain.

Cylinder head

An incredibly compact SOHC cylinder head positions the camshaft as close as possible to the centre of gravity to enhance overall handling and agility. Lightweight valves are actuated via a rocker arm while the timing is designed to create impressive torque and a precise throttle response. Connecting the head to the chassis, parallel frame mounts improve the chassis flex characteristics while retaining unrivalled stability.

Cylinder & piston

Weighing just 327 grams, the lightweight aluminium cylinder is an engineering masterpiece. Inside the 95 mm bore, the CP bridged-box-type piston features anodized annular grooves for added durability and longer service intervals. For improved peak performance, the compression ratio has been increased.

Gearbox

Manufactured by Pankl Racing Systems, the five-speed gearbox is low in weight while offering incredible durability. A Quickshifter sensor fitted to the shift drum ensures smooth upshifts at all times while a low-friction coating on the shifting fork further enhances positive gear changes.

DDS clutch

The FC 450 Rockstar Edition is equipped with a DDS (Dampened Diaphragm Steel) clutch. Unique in design, the exclusive characteristics of this system include a single diaphragm steel pressure plate, instead of traditional coil springs, with an integrated damping system for better traction and durability. Complete with a CNC-machined steel clutch basket adapted for the five-speed transmission, the single-piece component allows the use of thin steel liners and contributes to the compact design of the engine.

Brembo brakes

Brembo brakes deliver class-leading braking performance. With a 260 mm floating front disc, protected by a 2K carbon composite front disc protector, and a 220 mm wave rear disc, the incredible stopping power created allows for late braking, which leads to faster lap times. A new, stronger rear brake pedal tip is less susceptible to damage for continued control.

Map select switch

The intuitive handlebar-mounted Map Select Switch allows riders to engage both launch and traction control, enable the Quickshifter, and activate one of two engine maps. The easy-to-operate Map Select Switch allows racers to quickly alter the engine characteristics on a race-by-race basis depending on track conditions and rider preference.

Mapping

For a personalised power delivery, the FC 450 Rockstar Edition has two built-in engine maps as standard, which can be selected and engaged via the Map Select Switch. Map 1 offers linear, predictable power while Map 2 is more aggressive for a sharper throttle response and a more explosive power output.

Quickshifter

The Quickshifter function can be activated via the Map Select Switch and works by interrupting the ignition for a fraction of a second for smooth and precise gear changes, even when the throttle is fully open. To help prevent selecting neutral, the Quickshifter is only active from second gear upwards.

Traction Control

Traction Control on the FC 450 Rockstar Edition is engaged by pressing the ‘TC’ button on the Map Select Switch. Analysing throttle input from the rider and the rate at which engine RPM increases, if the RPM increases too quickly, the Engine Management System (EMS) registers a loss of grip and reduces the amount of power to the rear wheel to ensure maximum traction. This is a distinct advantage in wet and slippery conditions.

Launch Control

With the engine at idle, Launch Control is engaged by pressing the Traction Control and Quickshift buttons simultaneously. Both symbols will start flashing to indicate that Launch Control is activated. Designed for race starts, this technology limits the amount of power to the rear wheel, improving traction, and helps to prevent loss of control under hard acceleration. Once a gear change is made, Launch Control deactivates automatically. Additionally, Quickshift cannot be activated while Launch Control is engaged.

Electric start and Li-Ion battery

Keeping overall weight to a minimum and ensuring fast, reliable starting, the Li-Ion 2.0 Ah battery fitted to the FC 450 Rockstar Edition is approximately 1 kg lighter than a conventional lead battery. Additionally, the electric start and engine stop buttons are located inside the same housing for a simplified experience.
