Hey can someone tell me what size is the head pipe on the 1125r I need to know so I can order the pipe to make a y pipe. I'd just look at mine but the damn thing is still at the shop. | ||

The OD is 1.75" but it's typically oversized slightly by .020"-.025" or so. Just depends on where you measure it really. | ||

Dean, the headers are metric, 45 mm, which explains why you're getting the 0.020"-0.025" oversize. | ||
