Can anyone tell me if the 1991 fork legs are different from the 1992 on the 907ie? The bolts are 40mm apart, but is the location of the lug different? I have purchased 320mm rotors as well as new P34 Brembo gold calipers .Took a quick fit up without my wheel and it looked like they will work with my fork legs. ( My wheels are at the powder coater until the weekend.) If you have a 1992 ,could you measure the location of the lugs for me? I would greatly appreciate it. Thanks in advance.

The answer is "probably". The 1991 had 300 mm rotors, and the 1992-3 had 320mm rotors. Same wheels, and sometimes same calipers (black or gold) So yes, there are two different fork legs. No obvious visual differences.
Cheers, Phil

I have a 93 model with 320mm discs. As near as I can measure, the distance from the bottom of the fork leg to the centre of the lower caliper lug is 145mm.

With both a '91 and a '92 in the garage, it is easy to compare. The results are:
'91 Distance from centre of axle to bottom calliper lug: 110 mm '92 Distance from centre of axle to bottom calliper lug: 120 mm
It does make sense as the brake discs on the '92 are 20 mm bigger diameter, so 10 mm larger radius...
Sorry buddy, but they are not the same for exactly this reason...
