Sports Camshaft 336

BMW Airhead Boxer 336 Sports camshaft

BMW Airhead Boxer 336 Sports camshaft

Very similar performance to the iconic 336 sports camshaft as fitted optionally to the BMW R90S and others.

The 336 cam offers a much sportier profile than the standard 308 cam, with excellent mid range punch and a smooth, linear power delivery through out the rev range without sacrificing low engine speed tractability

Ideally suited for those riders that wish to have a Fast Road type bike, with an outstanding mid range power delivery and torque, especially useful for overtaking.


  • Lobe separation angle: 110
  • Inlet open 52 BTDC
  • Exhaust opens 104 BBDC
  • Inlet closes 92 ABDC
  • Exhaust closes 64 ATDC

Particularly well suited when fitted with the Dell'Orto PHM pumper carburettors. Please check out our Conversion kit.

Available for the BMW /5, /6 & R90S made up to September 1975 and for the later /7 & Monolevers manufactured after September 1980.
