For 1962 Honda introduced a series of production racers mirroring technology gained from their Grands Prix racers.
These were intended to provide suitable machines for good riders and obviously to continue the advertising success Honda were enjoying.
These 50cc items I covered in an earlier blog, but form part of this production racer series...
Likely for Japan only was offered a Super Sports or Clubman version of the CR93 racer, called the CR93 Benly racer Super Sports., same engine detail, with 16.5PS at 11,500rpm and 1.05kg torque at 10,700rpm, 5 speed gearbox, max. speed listed at over 135kph(84mph), dry weight 127.5kg, wheels and tyres as per the production racer. Price then 300,000Yen.
For the 250cc class, came the CR72 racer, a twin cylinder gear driven DOHC 4 valve per cylinder engine,247cc bore and stroke 54.0 x 54.0mm, twin carbs.,wet sump, 6 speed gearbox,29PS at 9/500rpm and 2.06kg torque at 7,500rpm 150kg dry weight, tyres 2.75-18 front and 3.00-18 rear, drum brakes front and rear with 2LS front and SLS rear.
There does not appear to be a directly related Super Sports road version.
The 350cc class had an enlarged type of CR72 engine, capacity 305.4cc, bore and stroke 60 x 54mm, 29PS at 9,250rpm .I have little other detail and leave it up to you to compare the photographs.
Then as mentioned before, Honda retired from formal Grand Prix racing around 1968 and it all became history…..
