So the NOC mag has an article on ‘Commando 961 Updates (Courtesy of Norton Motorcycles)’.
1) 36%/circa 350 part changes (which I suspect the majority are material, tolerance and finish).
2) Valve train re-engineered to significantly improve engine durability from 2.5 hours on test rig to 80 hours….
3) Changes to chassis frame, fuel tank, gear change rods, cush-drive rubber and more.
4) Sealed electrical connectors.
5) Gear shift durability improved with shift/mechanism changes and improved material/hardness Reducing risk of missed gears and selection issues.
6) Increased robustness of the camshaft to reduce wear.
7) Camchain guide has been improved to avoid bolt relaxation.
8) Changes to crankcase breather system to avoid oil carryover during high speed running.
9) Engine calibration changes to improve reliability, power delivery and the riding experience…
So there are a few items there that I was not aware of but the good news is that Norton have been re-calibrating the ecu (still assuming but don’t know whether it’s still an Omex).
