Im trying to see what the length on the front end of the frame(steer tube?) on my 1980 kz750e .It is for a front end swap. Is it the same length as a kz650

Same length.

What 650 is it? guessing a 70s model, but if it's a csr, the triple tree will bang against the 750E tank. pretty sure.

Im using a gsxr front end im looking at cognito for the stem just was wondering if the 1980 kz750 and a kz650 share th 're same neck size as hes asking fir the measurement. My bike is 16 hours away:(

From various frame diagrams at Partzilla the KZ650 & 750E use the same bearing races, so the measurements should be the same. The 92048-006 & 92048-008 races are used in a bunch of models. Additionally, All-Balls-Racing has a fork conversion lookup. enter a model, then see what other forks can be mated using the available tapered bearing sets.
