Anybody know if these 3.00 x17 tires for the CT90 will fit the on the C70??? I know they will fit the rim just wondering about rubbing issues. pretty sure the back will be fine, mostly wondering about the insides of the fork legs...any advice will be appreciated.

I know these 3.00 gazelle type will fit. looking for more of a knobby tire.

Also found these for a kawa ke100 3.00 x 17

Great bike you've got there. For the tires, 3" wide really is a squeeze, especially if you want to keep the fenders. I'd be surprised if they don't rub. I love that square-knobby tire. You should buy one, try it out on the front, and if it doesn't work, put it on the back and buy a 2.75 for the front.

Yea, that's a good idea. I was going to order 2 to save on shipping but I may just do one tire first. I don't think I'll keep any fenders on it and will probably chop it all up. I may put dirt bike forks on the front, and was thinking of a longer swing arm. Maybe some old mono shock swingarm... I have all kind of ideas in my head but making them happen is another story! Any suggestions or ideas would be welcome. Guess I need to start tearing into it and see what happens...

I don't remember ever seeing a monoshock on a Cub. The wildest rear suspension mod i've seen is a triangulated swingarm with the shocks laying horizontally next to the tank. A monoshock should be doable, as long as you really beef up the swingarm pivot point, maybe even upgrading the size of the bolt. Stock, the swingarm pivot basically just locates the front of the swingarm -- there's no real stress on it, but with a monoshock, there's a great deal of *downward* stress on that point. Imagine the swingarm as a lever, with the shock mounting point as the fulcrum.

I'd love to see that done, though. Would be cool.

Telescopic forks are always a great idea with these bikes. It's relatively easy to transplant the fork and wheel from some other bike, along with vastly superior brakes. Some front ends even bolt-up.

I've seen the mono shock setup, it maybe posted in my thread. I think you should get rid of that wacky rear fender, but that's me. I like to destroy shit, and make it better from the chaos! =)

Ideas on the rear mono shock placement. I thought about doing this too.


check out the rear shock placement on this Cubski about 2:10 seconds


Mono shock, i know it's the Honda Wave but in reality it's the same thing. Uses a trailing arm etc...

go to a junkyard with your swingarm
look for a dirtbike, or large streetbike you can steal the whole mono shock and swingarm setup off of it
something thats close to your width so it may just bolt in

there is that place in CV stockers

I need to hang out with you one day and go down there. Tom and I might sail the junk yard seas over the weekend. I want to see if we can find a quality carb off a big honda or something for the Gy6 life.

now back to mono shock you can weld a metal plate bottom and top of the swing arm to get it to work... just need bolt in tabs to make it work.

and find a shock that will work, and also not break apart on a long ride

as small of a space as you have if using stock I would look at those mountain bike shocks they sell different rate springs

if you have 12 inches a pit bike shock may fit up in there
should be alot cheaper for one of those

I've been scouring eBay for mono shock swingarms, most vendors don't list dimensions. A lot of older pw80 swingarm and cr swing arms match up in size but aren't long enough ,but could be stretched I guess. Thinking about a springer in front also, wouldn't have to be functional just mostly for looks...similar to the setup on the "independent" C70..

Need some help guys, will these 1969 ct90 forks fit on my 81 passport? Is the stem size the same? Can I run my hub and wheel or will I need that from a donor scoot also. I know some of you have done a lot of experimenting with different fork setups.Any other issues I may run into.
I found a decent set of for $100, Fair price? Any advice is welcome..
