Introduced at the end of 1980 the CB1100R benefitted from Honda's experience with their endurance and Formula 1 racers. The engine, although clearly derived from the twin cam CB900, differed greatly in detail. There were five plain main bearings complimented by plain big ends and the gudgeon pins connecting the semi-forged pistons to the conrods were 17mm in diameter. The cam chain was larger than the CB900 at 1.25 inches and the gearbox was refined to improve performance and heavier clutch springs were employed. An oil cooler was fitted as standard and a compact generator was employed. In stock form the engine delivered 120 bhp at 9,000 rpm and delivered a top speed of 148.21 mph when tested in 1982. Honda announced that the new machine would be limited to 1100 units in its first year, sufficient to allow homologation for production racing. The cycle parts reflected the CB1100R's intended use with a single seat, half fairing, adjustable clip-ons and a high flow fuel tap all being fitted. Suspension was provided by a set 37mm forks with air adjustable spring preload, increasing to 39mm with TRAC anti dive for the following season. Although monoshock rear suspension was becoming common on road and race machinery the CB1100R retained a traditional twin shock absorber system, Honda engineers considering it to be more durable and rigid than contemporary monoshock designs, although for the last year of production a box section swinging arm replaced the earlier, tubular assembly.
In total 4050 CB1100R's are believed to have been built over its three production life. This machine dates from 1982 and is described as being in very good condition in all respects having had only one owner from new, a Honda dealer in Switzerland. It has recorded only 26,000 Kilometres and has been maintained to a high standard throughout. Offered with Swiss documents and the original instruction book.
