1st | 2nd | 3rd | 4th | 5th | APPLICATION | |
3-SYNCRO | 2.57 | 1.72 | 1.26 | 1.00 |
Historic racers where homologated. Excellent fast-road ratios if you can tolerate no syncro on 1st gear! Works well for small-bore circuit racers and budget and grasstrack racers, but needs constant attention to 1st gear outer. |
|
4-SYNCRO | 2.58 | 1.71 | 1.25 | 1.00 |
CLUBMAN gear set. Ratios almost identical to above as this was conceived as a useful s/cut kit for the road, so same applications - but without 1st gear probs. |
|
2.54 | 1.73 | 1.22 | 1.00 |
ST gear set. Taller 1st gear and slightly closer ratios make it better suited to circuit racing, rallying, and the bigger capacity engines - ie. 1380cc plus. |
||
2.31 | 1.57 | 1.19 | 1.00 |
METRO CHALLENGE gears set. Very tall 1st gear originally designed for rolling starts, so less than ideal for static starts. Low FD needed if used for sprints or hill climbs, especially if 13" wheels are being used. |
||
JK 'DOG' | 2.31 | 1.56 | 1.19 | 1.00 |
Basic 4 speed non-syncro gear set. The one used by most circuit racers in UK where standing starts apply. Same details as above. |
|
2.16 2.16 1.75 1.69 1.68 |
1.56 1.48 1.36 1.36 1.36 |
1.19 1.19 1.15 1.15 1.20 |
1.00 1.00 1.00 1.00 1.00 |
These are all variations when alternative components are used. Taller first gears higher rolling start speeds. Super close rations minimise rpm drop between gear changes - allowing high revving engines with very narrow power bands to be kept on the boil! | ||
KAD | 2.62 | 1.99 | 1.67 | 1.29 | 1.00 |
5 speed non-syncro gear set. Only set available that has straight 1.00 top gear. Consequently fewer compromises to be made on serious racer. |
