Overview

Introducing the 2011 Fischer MRX, a standout entry in the competitive sport motorcycle category. Designed for riders who crave agility and performance, the MRX embodies the spirit of sport riding while delivering a unique blend of cutting-edge technology and innovative design. This motorcycle is aimed at enthusiasts who appreciate a lightweight chassis and precise handling, making it a captivating choice for both the track and spirited street riding. With its bold aesthetic and a promise of exhilarating experiences, the MRX positions itself as a formidable contender in the sport segment. At the heart of the MRX lies a robust 647cc V2 four-stroke engine, engineered to deliver an impressive 80 horsepower at 9,500 RPM. Coupled with 52 Nm of torque at 7,500 RPM, the MRX ensures that riders experience quick acceleration and an engaging power band. The engine’s advanced fuel system, featuring dual Mikuni 39mm carburetors, allows for responsive throttle control, while the computer-controlled ignition with variable mapping optimizes performance across various riding conditions. This powerful engine is paired with a 6-speed gearbox, providing smooth gear transitions and enhancing the bike's overall responsiveness. With a lightweight design of just 166.5 kg (367 lbs), the MRX boasts an impressive power-to-weight ratio, making it a thrilling experience on twisty roads or race tracks. The MRX is not just about sheer power; it also incorporates high-end technology and features that enhance the riding experience. The twin spar alloy frame, complemented by a trellis sub-structure, ensures both strength and agility, while the 43mm inverted telescopic front suspension with compression and rebound adjustment adds a level of customization to the ride. The rear suspension, designed by Ohlins, features adjustable ride height and damping, allowing riders to tailor their setup for their preferred handling characteristics. Additionally, the braking system, equipped with dual semi-floating 310mm discs at the front and a single 210mm disc at the rear, delivers exceptional stopping power, instilling confidence in every ride. The MRX also caters to comfort with an adjustable seat height of 749 mm, allowing riders to find their ideal position. **
