Overview

Introducing the 2007 Fischer MRX, a remarkable sport motorcycle that stands out in a crowded market, not just for its sleek design but for its unique blend of performance and technology. Born out of a passion for speed and innovation, the MRX was designed for the discerning rider who craves an exhilarating experience on two wheels. With an impressive collection of specifications, it represents Fischer's ambition to challenge the status quo in the sport motorcycle segment, making it a compelling choice for both seasoned riders and newcomers alike. At the heart of the MRX lies a potent 647cc V2, four-stroke engine that produces a thrilling 103.25 horsepower at 9,400 RPM, delivering power that is palpable and exhilarating. The 52 Nm of torque available at 7,500 RPM ensures a robust acceleration that will satisfy any adrenaline junkie. With a compression ratio of 11.5:1 and a dual Mikuni 39mm carburettor fuel system, this motorcycle offers a refined balance of responsiveness and efficiency. The six-speed gearbox allows for smooth, precise shifts, letting the rider harness the full potential of the engine while maintaining optimal control through tight corners and long straights alike. Coupled with a lightweight frame weighing just 175.5 kg (387 pounds), the MRX boasts an impressive power-to-weight ratio of 0.5882 HP/kg, making it agile and nimble on the road. Fischer has equipped the MRX with cutting-edge features that enhance both performance and rider comfort. The 43mm inverted telescopic front suspension, complete with compression and rebound adjustments, provides exceptional handling, while the Ohlins PR43 rear suspension ensures a plush ride over various terrains. Stopping power is equally formidable, thanks to the double disc front brakes and a single disc rear brake, which work harmoniously to instill confidence in braking performance. The MRX also includes advanced ignition technology with computer-controlled mapping, allowing for precise fuel delivery, and its electric starter ensures a hassle-free experience when firing up the engine. With a seat height of 749 mm (29.5 inches) and an adjustable configuration, this motorcycle caters to riders of different statures, making it accessible to a wider audience. **

Pros

  • Powerful Engine Performance: The 647cc V2 engine delivers impressive power and torque, providing exhilarating acceleration and top-end speed.
  • Advanced Suspension System: The combination of adjustable front and rear suspension enhances ride quality and handling, allowing for confident cornering and stability.
  • Lightweight and Agile: Weighing just 175.5 kg, the MRX is designed for nimbleness, making it easy to maneuver in tight spaces and during spirited rides.

Cons

  • Limited Fuel Capacity: With a fuel tank capacity of 17.03 liters (4.5 gallons), longer rides may require more frequent stops for refueling.
  • Carburettor Fuel System: While effective, the dual Mikuni carburettors may not provide the same level of efficiency and ease of tuning as modern fuel injection systems.
  • Niche Appeal: As a sport-focused motorcycle, it may lack some comfort and practicality features that touring riders might expect, limiting its versatility for everyday use.
