From the bike ratios spreadsheet they come out as follows
Primary Reduction 1.596
1st - 2.428
2nd - 1.823
3rd - 1.440
4th - 1.250
5th - 1.130
6th - 1.033
In practice assuming a 11700 red line (not sure if this is right or not?) - it makes it about 5mph higher in top at max revs compared with a blade,
using a 3.36 diff (128mph against 133mph). All according to the spreadsheet tho, not sure if its accurate or not. I'll email it across to you
though so you can have a play
