Anyone know what the diameter measurement (in mm) is of the top of the front sprocket bolt on a NC29?
I am looking to see if the speedo drive thats standard on a NC29 will slot over the bolt thats holding in the Hybrids front sprocket as it does not have a working speedo.

Having recently brought the plastic bit for my 29 it's the same part as that on a hornet, I would suggest your 600 engine would be the same

I use the 29 drive in a hornet sprocket cover on my pc25.
