TRANSMISSIONS
From an early /2 thru R1200 series and K bikes we are able to update and repair your transmission. We can check and rebuild your transmission, update internal components, and undercut gears in M series transmissions. We use only top quality NTN, Koyo, or Timken Bearings. We also solve known problems by modifying or changing a bearing or transmission case thus creating a reliable transmission. We offer a core exchange for some transmissions.
Don't be fooled by a cheap rebuild.
AIRHEAD TRANSMISSIONS
Rebuilt 1974 - 1995 series - New bearings, seals, new gasket, pawl springs, and reshimed.
$595 - $650
OILHEAD TRANSMISSIONS
What exactly is undercutting the R1100 Transmission gears?
The transmission gears lock together with a series of "dogs' or "dogs and slots". Under use, the gears can begin to separate until the dogs become disengaged, this causes the transmission to jump out of gear. TTttttTypically third gear UndrU
Now notice in the photo the dogs that are in the circle. They both have angles cut on them where they meet. This causes them to lock together. They cannot separate without first backing up to unload the angles. This is an undercut.
Undercutting the 2nd and 3rd, 4th and 5th gear prevents the fork wear and gear slipping that plagues certain R1100 M series transmissions, typically third gear. A careful rebuild works well with gear undercutting.
