Does anybody know if a front wheel from a 1969-71 Yamaha DT1 or an RT1 will bolt right onto a CT1 front fork without any trouble, or is there a better way to go about puting a 21 inch front rim on my CT1? I hate having an 18 inch front wheel because there is not very good tire selection available for 18 inch front wheels in offroad tires, so I want to convert it to a 21 inch front rim. I'm thinking about buying a DT1 or RT1 complete front wheel off of ****, but don't want to waste the money if it's not going to work on my CT1. Does anybody have thoughts on this?
