Small and per­fectly formed

Classic Racer - - WHAT'S INSIDE -

After so much pos­i­tive feed­back to the fea­ture on Pete Parn­ham’s lovely lit­tle CR110 in the last is­sue, I had to scour the archive to re­veal more de­tail on the lit­tle gem. Thanks to the de­vel­op­ment of the fac­tory rid­ers in 1962 the cus­tomer CR110 had an amaz­ing spec­i­fi­ca­tion, 8.5bhp at 13,500rpm and four tiny valves con­trolled by dou­ble valve springs. The big end and main bear­ings were nee­dle roller and the crank-pin was in­te­gral with the drive side fly­wheel and main shaft. The gear­box boasted eight gears, amaz­ing for the pe­riod with all gears in con­stant mesh with an al­ter­na­tive link­age to al­low swap­ping the lever from the left to the right. The clutch was hy­drauli­cally op­er­ated by a col­umn of oil through the hol­low main shaft rather than a pushrod. In­cred­i­bly, the high revving power plant runs on one pint of oil! One inch Kei­hin carbs feed the en­gine, sparked by a sin­gle 10mm spark plug. In 1962 the CR110 cost a pricey £330, only around £100 pounds less that than a Manx Nor­ton! But the jewel-like ma­chines were def­i­nitely the tool to have in 50cc rac­ing and went on to dom­i­nate. To­day they fetch an equally spicy price and are much sought after by col­lec­tors.
