[the gap between the forks]

im trying to fab up a somewhat unconventional headlight bracket and i need the measurement.

i tried taking a pair of calipers out but the arms aren't deep enough (cheap caliper) and there is so much interference, im not sure im getting an accurate read.

i could just pull the triple top end off... but thats a lot of work before checking if someone has the number laying around

 

Take your handle bars off and measure between where the forks stick up through.

 

yeah... was trying to avoid work in the off chance that someone had the number handy...
