CB360 - Penelope

dam this rocket looks cool!!
wish I could photoshop an idea of a tail for you.. but I'm still learning this new computer.. and it's got me baffled half the time.. LOL

But maybe I can translate in word what I see? LOL
Kind of a reverse of the tank.. way smaller of coarse.. But start narrow and flare out before wrapping around back. If that makes sense? HAHAHA
 
What CAD software do you use? Or did you use? Someone had mentioned SolidWorks, but it doesn't look like it. Unless maybe you are using a different rendering program? I've got a few years of SW under my belt but nothing too crazy. Mostly self taught...

All of the stuff for this project has been done in Solidworks. It is what I learned in school, but now in the automotive engineering world, we use Catia...Solidwork's bigger brother.

Very cool stuff man. I need to step my SW game up I see. Thanks for the insight. I'll have to check out Catia sometime. Cant wait till you fire that thing up. I've got a 4-1 (Mac?) on my cb350f right now. I question the brand because there are no marking; BUT there is a MAC sticker on the rear shock... hmm. Bike isnt running so I dont know what it sounds like.. yet. :) Carry on!
 
After a few too many comments about this bike looking squished I finally measured everything. Maybe it was my ignorance in not want to re-do things, but it looks like a longer swingarm is in order. My wheelbase currently is about 49 inches, which is about 4 inches short of stock. I think my scrap metal swingarm was in fact .75" shorter than stock meaning that with those gsxr forks, the front wheel has moved back almost 3 inches! Maybe I need to keep measuring...

Anyone else with a stock (or nearly stock) 360 want to measure the distance from the front wheel axle to the swingarm pivot for me for comparrison? And also the rear axle to the swingarm pivot? Shortest distance should work fine

Thanks for the help!
 
Just measured mine.
Front axle center to swing arm pivot about 35".
Swing arm pivot center to axle center with chain adjusted, exactly 18-1/4" (little less than half way along adjuster slot)

Thanks PJ! I appreciate it!

Comparing these numbers to mine, the front wheel is only 1.5 inches back, not 3...but that is still considerable, and my swingarm is about an inch short.

Definitely time to make a new swing arm and stretch this thing out to more normal proportions! This one should be a little more accurate. It will give me the ability to increase the angle of the rear shock, effectively increasing the motion ratio and making better use out of the current spring.

Thanks again guys, back to the drawing board!
 
Aesthetics aside, you can also drop the rear a bit in order to regain a bit of trail. Short wheel base is good for maneuverability so long as stability is there.
 
I just bid on some GSX-R triple trees on eBay, I'm going to do Gixxer forks on 'tracker' ::)
Extra trail should bake it reql stable when I get it 'slideways' ::)
 
Nice PJ! I'm curious to see how that is going to turn out!

I know what you mean Sonreir, but I think I would actually rather lower the front and raise the rear (a tiny bit) from an aesthestics stand point to give it an aggressive stance. I'd rather things pointed down and forward instead of up, if that makes sense. For example, I have been trying to keep the bottom line of the gas tank horizontal, or slightly downward.
 
In order to work on Penny I need to be able to get her to work so I can utilize the tools there. Instead of breaking her down piece by piece I decided to make a hitch mounted hydraulically assisted motorcycle carrier, here it is:

This is REV A of the platform...I kind of over built it. It weighs 90 pounds and is obnoxiously stout. REV B will weigh less than 40 pounds but still be plenty strong.

Roll the bike on and jack it up

That gap is no accident!

The anti-rotation hitch pin is not installed, but once it is, the platform will not rotate

Man get and market these to somebody, unless you have the facilities to make thousands yourself! Fantastic engineering. :)
 
I'm far from any kind of engineer, but is a bottle jack rated for any kind of shock load (with the bike loaded and the truck going over bumps)? I do know that they can develop slow leaks, which could lower the rack over time, but a sudden hydraulic loss could result in a spectacular spark trail.........
 
I agree, your build is freakin awesome. And you do need to position yourself so that it can go faster...I cant wait to see her done.
And the hitch is SUPER COOL. but i would have to install air shocks on my Honda Fit!!!

I already have an early pic of your bike on my blog. Would you mind if I post another?
