This 310LB Carbon-Clad BMW Pays Homage To Battle Of The Twins Racers

While it doesn’t hold the same level of prestige as it did in the 1990s, the Battle of the Twins race at Daytona was once a go-to proving ground for motorcycle manufacturers. And it’s the machines that competed at this once-iconic 50-mile event that inspired custom motorcycle builder, Scott Kolb to churn out his latest project: a feather-light, carbon-clad BMW race bike.

The Bavarian airhead was ported and fitted with dual spark-plugged cylinder heads, bigger valves, an up-specced flywheel, a race-grade clutch, a balanced crankshaft, and a Siebenrock big-bore kit that bumps displacement up to an even 1,000cc’s. The build also sports a fully-bespoke two-piece trellis frame made from 4130 Chromoly tubing that utilizes the power-plant as a stressed-member and sees a matching, custom trellis-style single-sided swing-arm bolt directly to the engine. The one-off framework is adorned in custom-made carbon fiber bodywork and a knee-dented aluminum tank. The Beemer also boasts Ohlins suspension, Brembo brakes, Rotobox RBX2 carbon fiber wheels, and a smattering of Rizoma and Motogadget bits. All the modifications, carbon, and customs work allow the completed bike to generate 82hp while tipping the scales at 310lbs — a far cry from the ’76 R90/6 donor’s 60hp and 462lbs weight.
