Difference between 1.85/2.15 rim

[KGB]

talk about reinventing the wheel.


Swap out the front end, voila simple enough.
No need to worry yourself over sizes of tubes and if
this leg from this model will fit.

The issue could still be, will that 2/nd disc fit in between the forks ?

But like Terry said, I don't want to mess with the front geometry too much! Why's this sh*t so complicated!!!???

You can slide the forks 17mm up into the triple trees to offset the length.

Not the wheel... just the bits that attach it to the rest of the bike
In my case, I did try to slide the tubes up in the trees. It still didn't feel right.
I also tried a full front end swap. I would have had to grind the lock tab off of the G model triple tree to make it work. (viola indeed!) I wound up swapping the dual disc outers onto the stock inner tubes. Presto! Handling harmony was restored. the second disc fit fine.

The 750T is unique in many ways. Specs are hard to find. That's why I asked for measurements.

So all I'd need is a mm caliper on the inner tube to find it's diameter, and then measure the length of the outer tube(the part the brake calipers bolt to) right? When measuring the length of that outer tube, I'm assuming I need to pull back the dust cover and measure from the top there, to the middle where the axle goes in? Or maybe the sides where it attaches to the bottom bracket?

That should do it. I'll compare measurements to my dual disc 750E & 1000E & see if they match up.

Okay, looks like they're 35mm forks.

Wow, Talk about complicated. When I did the swap on my 650L, I just bought the front end from a 650G, and Plugged everything in. I ended up using the forks (upper and lower), calipers, and discs from the G and the front wheel, axle, speedo drive, and some spacers (not all) from the L. The wheel was already drilled and tapped for dual discs. The trick to making it all work was the speedo drive. They also act as spacers, and the drive from the G was too wide for my L...Took a couple of days to figure that one out. Anyway, it handles fine, if not a little bit heavier in the steering. That could be due to the extreme change I made in my handlebars though. IMHO I would look for a front end from a 750G, and try the swap with that. You could also look in your service manual...You have one right...and compare specs with someone who has the specs on a 750G. If you don't have one...well PM me...I'll see what I can do for ya.

No such thing as a 750G, is there?

[UncleMike]

I assume going from 35mm to 37mm forks is desireable from a handling perspective?

No it will throw your carbs out of synch

You will notice some, minor, not a huge difference in the stiffness
of the front end.


So now what size tire can you run ?
Get rid of that Kenda..............

Mike, if you're going to upgrade anyway why not go for something newer? You could go with an '83 and up 700 or 750E front end that would look correct to the casual observer and they can easily be pulled up or down in the triples if the length needs to be worked with. You'd have the quick 16" front wheel too. I have calipers lying around for one if you need some. They are probably the same as were used 4 or 5 years earlier on the 750's. With all the guys doing upgrades you should be able to pick up a front end cheap whatever you decide to do. I'm going to have an '88 GSXR front end available soon but it would be better on a 550 with a heavier rider.

The Kenda is on my spare set that I'm selling from my old 750L. I've got a Dunlop up front on my T.

I'm not sure that a 16" wheel would look right on the T. I picked up a front end from an '80 1000 on ebay including forks, calipers, triples, signals and fender, with SS lines for $79.

I might just take the SS lines off of that and mount some 750 forks on, so I can keep the 19" front wheel.

Ya. In 81 and 82 they made a 750GL with dual discs. Check the Gallery page. Thought about using a front end from those for my bike, but I think the uppers were bigger diameter than my 650.

Weird. I could've sworn G = shaft.

[8trackmind]

Mike, you're over-thinking this.
The left side is easy. Speedo drives on all models are the same thickness. Done.

Read this to adjust the right side.

No balance issues, nothing to it. I have at least 4 different years of parts bolted to the front end. No problem.

You know, you may not even have to do anything to the right side spacer.
