1992 HONDA NR750

Classic Bike (UK) - - EVENT -

Honda re­turned to GP rac­ing in 1979 and tried to beat 500cc two-strokes with a four-stroke. Their NR500 V4 over­came the four-cylin­der limit with oval pis­tons on twin con­rods – it was ef­fec­tively a V8 with shared com­bus­tion cham­bers. Pis­ton shape al­lowed eight valves per cylin­der, help­ing with their 23,000rpm tar­get (they needed twice as many revs as the two-strokes to match their power out­put).

The 500 failed. How­ever, af­ter con­tin­u­ing de­vel­op­ment in the NR750 en­durance racer (which qual­i­fied sec­ond at Le Mans in ’82), the tech reached the road with the sub­lime NR750 in 1992. Just 200 ex­am­ples of the exquisitely-engi­neered 32-valve mas­ter­piece were built, and this ma­chine from the Wil­low­brook col­lec­tion is a Swiss mar­ket model. It’s cov­ered just 1408km and comes with its orig­i­nal bat­tery (hav­ing been kept on a trickle charger), tool kit, paint touch-up kit and pad­dock stand. With Swiss pa­pers, it’s es­ti­mated at £60,000-80,000.
