While the original V-Rod (VRSCA) shocked the traditionalist market, the VRSCB (B-Modell) was the first true evidence of Harley-Davidson’s commitment to the platform’s evolution. A unique engineering highlight of the VRSCB was its move toward a more ‘raw’ aesthetic, replacing the silver-painted frame of the ‘A’ model with a striking black powder-coated frame and adjustable handlebars. It maintained the legendary 1130cc Revolution engine—a powerplant co-developed with Porsche Engineering—utilizing dual overhead cams and four-valve heads, which was a radical departure from the air-cooled, pushrod architecture of the era.
Technical Performance & Handling
The VRSCB is defined by its high-revving nature, with a redline reaching 9,000 RPM. This requires a chassis capable of handling significant torque. The B-Modell features a slightly different ergonomic setup than its predecessor, offering a more aggressive riding position. The liquid-cooling system is expertly integrated, utilizing a large radiator shrouded by air scoops that have become iconic to the V-Rod silhouette.
Maintenance Guide: MotoSpecsLab Standards
To maintain the high-performance integrity of the Revolution engine, strict adherence to fluid and ignition specifications is mandatory. This is not a standard air-cooled V-Twin; tolerances are tighter and thermal loads are managed differently.
1. Lubrication System
The VRSCB requires 4.3 liters of high-quality lubricant. MotoSpecsLab recommends Screamin’ Eagle SYN3 20W50 for superior shear stability at high RPMs, though Harley-Davidson 360 20W50 is acceptable for standard street use.
2. Tire Pressure & Contact Patch
Maintaining correct tire pressure is critical for the V-Rod’s unique geometry (38-degree rake). Under-inflation leads to heavy low-speed steering and accelerated cupping.
– Front: 2.48 bar (36 psi)
– Rear (Solo): 2.48 bar (36 psi)
– Rear (Two-Up): 2.76 bar (40 psi)
3. Ignition & Electrical
The VRSCB utilizes the 65948-00B battery. Given the high compression ratio and electronic fuel injection, a healthy cold-cranking amp (CCA) rating is essential. For the spark plugs, use HD 10R12A or NGK DCPR8E. Ensure the gap is precisely set between 0.97 mm and 1.09 mm to prevent misfires under load.
Conclusion
The VRSCB remains a pinnacle of ‘Muscle-Cruiser’ engineering. By combining the precision of German engineering with American styling, it offers a riding experience that is both visceral and refined. Proper maintenance using the specifications above ensures this modern classic continues to perform as intended.
