Pics of the 150/90 15 rear tire
« on: March 27, 2006, 03:10:21 PM »
You asked for it, here it is.  This is a 150/90 15 rear tire on my 77 cb750.  The bike is pretty much stock other wise.  The only other changes are Ducati Fork Ears, and a Triumph Rear Fender.   The one pic shows the close clearance from the torsion Bar and the swing arm.
Enjoy, I know I do.

No probs Joe, by the way did you ship those light?  I have to go do my road test for my full M license this year and I know those stubby signals I'm sporting are not legal.  Do you all in the US and the land of Oz also have the Graduated license thing??

New York State: Go to the DMV and take a written test to get your "Learner's Permit" which allows you to ride while within 1/4 mile of a fully licensed person or some such nonsense.  Good for a year. 

Then you take a road test for the full license.  An alternate route is to get your permit and then take the Motorcycle Safety Foundation (MSF) course which combines classroom & driving instruction, the last of which will suffice for the DMV road test (road test waiver, actually).

The MSF course is highly recommended, particularly for guys like me with no road experience.

Duh, I guess I have done the Dual Front Disk conversion as well, meaning the dual disks and a 750F master cylinder, that's not stock.  Should have been though you double those babies up and you can stop on a dime.

Chundy - would you like to write up the mod for us.

There have been many "What's the largest rear tire I can fit..." threads here.  This seems to answer them!

sweet bike dude! did that triuph fender mount right up, or did it take some fanagling?

in minnesota you take a written test for your learner's permit. you are required to wear a helmet, stay off of interstates, and ride solo(no passenger) until you get your license endorsement
or you can take the written test and enroll in the MSF course, once you graduate you automatically get the endorsement

In New Mexico you do not ever need a helmet nor a motorcycle license endorsement.  I'm not saying we're the smartest people, but we do have us some fun. ;D

Took a couple of holes being dilled, that's it.  Was actually done by TinTin (My SOHC Mentor)and his buddy.

F's don't convert easy at all, that being said there have been some butchers in Japan that have done conversions.  They were into refabbing swing arms and swapping out entire brake system.  Let's just leave the fatty wheels to us K riding boys. if you want to see some of the hack jobs i can give you a link to my fav, just not sure how this site feels about links.

i would damn sure like to know where you found a 15 inch rim.

15" rim is off an older Harley, yeah I know worlds are coliding, but hey they saw no need to make one in Japan.
As for the spokes, well you would be into having to know somebody into custom work, or be handy yourself.  The ones I have are actually custom, and only about a 2 inches long.  I can post some more pics over the weekend of the detais.

Something else I have just noticed, now that I have been looking.  The Chinese are making alot of 15" rear wheels.  Check em out on ebay, cheap like Borsh.  Could make for a fun project.

Something to consider; The larger diameter rear rim you use, the narrower the tire must be. I run an Avon supervenom 130/90 on a stock size 18" rim. You may be able to get away with a 140/80, but the taper of the swingarm gets very close to the shoulder of the tire.Also, if you ride hard enough, will the tire twist enough to make contact with the swingarm? I won't risk my hide to look cool with a fat rear. Wait... that doesn't sound good! Shiny side up, please.

I won't risk my hide to look cool with a fat rear. Wait... that doesn't sound good! Shiny side up, please.

This brings me around to what I've been thinking about lately- I want to have fatter tires on my CB550..  The reasoning being that the fatter the tire, the bigger contact patch.  This would allow for more traction, and better stopping, etc.  I just learned from reading here that you can't stuff a wider tire on the same size rim, as it doesn't work right.  So, you need a wider rim to run a wider tire.  And, if I want wider wheel/tire, I gotta use a smaller diameter, right? 

So, what do you look for when you are computing everything to figure out what size rear wheel, tire, etc. to make/buy?  If you get a smaller diameter, wider wheel (so you can run that wide tire), do you get a taller tire, so that ultimately you have the same ride height in the back (i.e., the outside diameter of the new wheel/tire is the same as the stock wheel/tire?)

Finally, how can you compute what size tire to put on a known size rim?
