Can anyone that has their sprocket or wheel off measure the diameter of the centre hole on the sprocket OR the part of the hub on the wheel that it fits over please? Supersprox don’t list a rear sprocket for the double sided swingarm model yet but they may already make one, they’ve asked me to measure but my bike isn’t in my garage yet, they’ve asked thought it will be either 73 or 76mm If I get an answer & they make one I’ll post the info back on here. thank you
