Hi All

Trying to work out the ratios of a Kombi Two litre box with reduction hubs on it. I trying to find a formula or the likes to work out the rpm with various tyre sizes at 100 km/h perfer I go tyre shopping.

2lt standard box (think) with reeduction hubs (no idea of the gear set in these. I could to a spin and measusre test if this helps.)

Can you still buy gearsets for the reduction hubs?

Cheers Brendon

Are you sure you have this right? how are you going to put reduction boxes on a 2L irs gear box?

The stock reduction geared boxes came with the early 1200 and the later 1500.


Anywho calculators.
