Unleash track-day performance with the Marchesini M7R Genesi Forged Magnesium Rear Wheel for your 2002-2003 Yamaha YZF-R1. Achieve significant weight savings, superior handling, sharper acceleration, and World SBK/MotoGP aesthetics. The ultimate performance upgrade.
Elevate your 2002-2003 Yamaha YZF-R1 to a new level of performance with the Marchesini M7R Genesi Forged Magnesium Rear Wheel. Born from extensive experience in the highest levels of racing, including MotoGP and World Superbike, the M7R Genesi brings genuine motorsport technology directly to your motorcycle.
This aggressively designed, 7-spoke wheel is crafted using a specialized, multi-directional closed-die forging process with high-resistance, aerospace-grade magnesium alloy (ZK60A). This advanced manufacturing results in a material with exceptional mechanical properties and an unrivaled strength-to-weight ratio.
By drastically reducing both unsprung and rotational mass—achieving weight reductions of 26% to 41% compared to the original equipment (OE) wheels—the M7R Genesi fundamentally transforms your bike's dynamic characteristics. Experience explosive acceleration, significantly shorter braking distances, and instantaneous, nimble handling. The meticulously engineered 7-spoke structure is optimized via FEM (Finite Element Method) analysis for maximum stiffness and rigidity, ensuring precise steering and enhanced rider feedback under extreme cornering and braking forces.The wheel is finished with a durable, high-quality urethane coating and includes a new ring-type damper system for reliability and weight reduction.A special Marchesini sprocket is required for installation (sold separately).
Best Uses
1.Competitive Track Racing: Essential for professional and serious amateur racers looking to reduce lap times by minimizing rotational inertia and maximizing dynamic performance.
2.Track Day Enthusiasts: Provides the single most significant handling and acceleration gain for dedicated track riders.
3.High-Performance Street Riding: Elevates the agility, braking, and responsiveness of the YZF-R1 for spirited and high-speed road use.
4.Premium Motorcycle Builds: The go-to choice for enthusiasts who demand the ultimate in motorsport technology, performance, and aesthetic prestige for their machine.
Features
1.Aerospace-Grade Forged Magnesium: Manufactured from high-resistance, aerospace-grade magnesium alloy (ZK60A) using a precise, multi-directional closed-die forging process.
2.Radical Weight Reduction: Achieves a weight savings of 26% up to 41% compared to the Yamaha YZF-R1's original equipment (OE) wheels.
3.Optimized 7-Spoke Design: Structurally engineered with a fluid spoke profile for maximum rigidity, even distribution of radial load, and reduced aerodynamic drag.
4.MotoGP/World SBK Proven Pedigree: Directly adopts spoke and hub design principles from the wheels used by top-tier factory race teams in global championships.
5.New Ring-Type Damper System: Features a newly designed damper system to enhance durability while contributing to overall weight reduction and improved torsional control.
Benefits
1.Explosive Acceleration: Dramatically reduced rotational inertia means less engine power is wasted, translating directly into significantly faster initial and mid-corner acceleration.
2.Superior Handling & Agility: Reduced unsprung mass allows the suspension to react quicker and more effectively, resulting in faster lean-to-lean transitions, more nimble handling, and improved feel.
3.Shorter Braking Distances: The lighter rotating mass requires less braking force to slow down, improving overall braking efficiency and feel, especially under hard deceleration.
4.Enhanced Rider Feedback: The high rigidity and precise engineering provide the rider with clearer, more accurate feedback from the rear tire's contact patch, increasing confidence.
5.Unmistakable Motorsport Aesthetics: Instantly upgrades your R1 with the aggressive, iconic 7-spoke design and the premium prestige of a genuine Marchesini racing component.
