    I'm in the process of modifying a CT70 and one of the things I want is 12" wheels. I'm going with a +2 swingarm from Tbolt but I have a handful of questions regarding the idea of 12" wheels. Tbolt also has a set of one piece aluminum 12" wheels that will bolt onto the OEM hubs. I don't hate them, but I'm wondering what my other options are. I've looked pretty hard but don't really know what will work and what won't when it comes to 12" wheels.

    - Does anyone make a 12" version of the oem 10" rims??? Just basic steel 112" rims. I haven't seen any.
    - If I google 12" scooter/motorcycle wheels, I get LOTS of results. These come complete with hubs for the most part. Do the CT70 brake hubs fit into most/all of these??? Is this a standard size hub if that's even a thing???
    - I'd like to keep the stock front forks but would like a disc brake on the front if I can. My CY is a 1974. Can I just get a front hub with a disc mount and then get a mount for the caliper to mount to the stock CT fork lower? I've seen this setup on quite a few modded CTs on the itnernet, but I can't find anyone that sells anything to make this happen. This is something I'd really like to do. I know I can buy a complete front end that would have all this but I'd like to keep my stock front forks if I can but I'd rather stick with the factory fork setup.

    I'd love to hear what everyone has to say about this topic. I'd like to think I'm fairly experienced at searching for things on the internet, but I'm having a hard time with finding info on wheel setups that I can be assured will work.

    Thank you!

    Howdy, I was also considering going to a 12" rim myself, after riding my son's new Monkey and seeing how much more stable it was at speed. I was looking at the cheapest way to go and figured by buying a used Chinese pitbike, I'd get the 12 inchers as well as disc brakes for a song. It just would be a matter of making everything fit. But then I saw a bike with larger scooter tires and tried a set of 120/90-10's on my CT. Now it feels so much more stable at 50 mph and corners with a lot more confidence, I'm gonna stay with this for a while, maybe go with some upside down front forks with a front disc after I get my bigger motor.

    You have just about the largest (safest) tire that fits the 10” rims. Stay with that if your happy. If you move up to 12” wheels the tire you will end up with will have the same diameter anyway. Use an online tire calculator if you don’t believe me. I run 120’s on mine. Have for years. I really like them.

    I appreciate the information and the hearing about your experiences! Staying with the stock wheels but using 120s on them sounds like a great plan.
    Thanks again!
