Practical Sportsbikes (UK) - - The 1990's -

The CB1100R was Ja­pan’s first four-stroke ho­molo­ga­tion-spec prod­die racer, a class that would go on to form the back­bone of sports­bike de­vel­op­ment for the fol­low­ing 20 first glance the 1100R looks lit­tle more than a dressed up, bored-out CB900F. But Honda built the 1100R to win races

The tubu­lar steel cra­dle frame, for ex­am­ple, de­rived from the CB750/900, was more rigid thanks in part to the pre­vi­ously re­mov­able lower left rail be­ing welded in place.the 37mm forks were air-as­sisted (later RC/RD mod­els got 39mm TRAC unit), pig­gy­back Showa shocks were fully ad­justable, the light­weight alu­minium fuel tank was hand-welded, and the mo­tor shouted ‘trick’ from its forged pis­tons, saucier cams, beefed up pri­mary and 33mm Kei­hin carbs. It was as trick as four-strokes got in ’81.

It worked too, win­ning both Aus­tralia’s and New Zealand’s then mas­sively pop­u­lar Cas­trol Six-hour races, as well as nu­mer­ous pro­duc­tion races and ti­tles in the UK in the hands of Ron Haslam, Joey Dun­lop and­wayne Gard­ner.

Given the im­pact of the RC30 that ap­peared seven years later it’s easy to over­look the CB, but this bike paved the way for it.
