Cool Upsidedown forks/lowered clip-ons

Hey Riders!

I'm thinking of a suspension swap or clip-on swap. Share your experiences and your bike if you did yours!

Thanks,

Tim

What will different forks do for you the OEM forks do not?

The OEM forks have pretty terrible damping characteristics, springs that are progressive and soft, and no compression, rebound or preload adjustment.

As far as fork/clip ons, I put in some preload adjusters ($40 bucks or so on ebay) that worked really well, though given my weight (~100kg) I had to adjust them all the way. Will have to get new springs at some stage...

Put on some ebay clip ons above the triple tree. I don't see how you could fit them under without hitting the fairing or having clip ons with ~1 inch rise.

This is for a track bike mind you, so comfort isn't anything I'm looking for.

There is the Rally Raid fork upgrade. I believe they have straight rate springs.

Aha. Track bike. Whole different world.
Good luck, and please let us know what works for you.
Thanks.

Racetech and a number of suspension specialists have straight rate springs that will suit.

I'm not aware of any people who've swapped forks for better ones, though they're 41mm diameter so there should be options out there.

Honestly, it's probably easier to replace the springs and get a cartridge kit than to swap forks, unless you have some cheap ones that will work on hand.

The CB has damper rods to control fluid flow. It's ok for the street but for the high demands of track days it would be better if you had the real deal.
Your concern is fork tube diameter and length. Upside down forks are out of the question without changing the triples.

Have you tried contacting suspension specialists for dimensions?. They would be the best bet for knowing the fork dimensions between different brands.
41mm sounds familiar, I'll go out and measure my other bike and see what they are.

I got nothing. My other bike has a 43mm fork and the other one has an upside down fork.
I would talk to suspension people or go with one of the Rally Raid set ups.

Or try to find a front end from a sport bike that will fit your triples. That way you could get dual disk brakes up front. Maybe just have to deal with spacers and bushings.

I did a full upgrade to the stock forks with Racetech .85 springs, Emulators, and pre-load adjusters. I am happy with the results, but it depends on your riding style if it is even necessary or not for you to go through the work.
As for a full fork swap, I think I read somewhere that a guy swapped out the entire front end to a CBR600 front end including brakes and rim. Not sure what year 600 he used though. Will have to try a little searching around and see if I can find the thread.

Currently placing my vortex clip ons under my triple tree. Have just about everything ready to go. But I'm still trying to achieve full lock and right turn throttle spring back is sticking. So my cable is binding up somewhere.
