AJR/Bultaco 350 TSS Close Ratio 6 Speed Gearbox
For all our products see our full product list
We have re-designed our Nova 6 speed gearbox up to our latest specification. This includes billet machined selector forks, dogs re-designed to give slicker shifting and less backlash. Also we have changed the ratios to allow for stronger teeth to increase strength and durability. Various ratios are available to give maximum performance on both short and road tracks.
We supply the input and output shafts assembled and ready to fit, along with a new selector drum and 3 selector forks.
