The BMW R1100S is a sports motorcycle that was manufactured by BMW Motorrad between 1999 and 2005. Introduced some 25 years after the R90S, the company's first sports bike, the R1100S was the first BMW bike having clip-on handlebars, rearset footrests and a removable cowl to cover the pillion seat.
A special edition model was the R1100S Sport, which was a standard R1100S fitted with an optional "Sport" pack comprising stiffer suspension via a taller rear monoshock, a steering damper, and a wider rear wheel and tyre. Bike magazine commented: "The basic R1100S is good value, but we're not convinced that the high spec Sport version offers any real benefit for road riders".
A more expensive track-day version of the BMW R1100S, the BoxerCup Replika (or "BCR"), was available from 2003-2005. The BCR had twin Laser under-seat exhausts, braided brake lines, carbon-fibre cylinder head protectors, a carbon-fibre oil-catcher bellypan, uprated Öhlins suspension, and a shorter paralever torque arm which raised the rear end to quicken the steering and increase cornering clearance. Later BoxerCup and Sport models had matte black engines, with the cylinders and cylinder heads remaining silver.More specs and user manual of BMW R1100 S you can see in next overview.
The raised suspension of the BCR increased cylinder head cornering clearance (compared to the standard R1100RS), but this somewhat compromised the motorcycle for normal town/road use.
The BCR came with a standard engine management chip which was changed for a modified chip at the first dealer service. Despite the different chip, the Replika claimed no more power than the standard R1100S nor the Sport.
