17" wheel GSXR conversion

This could be a cheap alternative to maintaining ground clearance

stepped triple

Yep its an old trick but a good one

far cheaper than having a proper stepped top yoke machined

Often wondered if anyone did this....someone needs to tool up and build these things.

I like the idea...

I wouldn't like the idea if I were any of you. You're putting all the stress the upper clamp sees on a MUCH smaller and MUCH weaker area.

However, the concept is great.

A BETTER way to do it would be to weld two triples together and ONLY cut out what interferes with steering. You will have a much larger weld and a much stronger part. Hell, if done right, you could cut the clamps off the top top triple and slope the metal down to where it looks as though it was meant to be that way.

And this has nothing to do with 17" wheels. You don't have to do ANY suspension modifications for the wheels alone.

Might as well have one machined..it would seeem a bit bulky with two welded together.

yeah I'd much rather have two thin welds holding the front end of my bike in air instead of something "bulky".

Everyone is entitled to do whatever they please, it's just my opinion that welding two clamps top to bottom alone is not the safest way to go about it. It would be much stronger to carve out the steering stem area on a second triple and have a large, SOLID piece holding the whole thing together. No need to have anything machined.

 

[jwhelan65]

ok, I think I struck a cord here, I don't disagree with your method. I actually think its a good one. First and foremost I agree safety must always be addressed before doing any modification. I also think that mods need to look like they fit the lines and integrity of the bike. No harm no foul here, just my opinion.

 

[makenzie71]

not worried about it...just saying, is all.

I did not fully elaborate, but when confronted with the problem of ground clearance due to 17" wheels, one looks for ways of increasing ground clearance. Other that raising the exhaust, raising suspension height is the next alternative.
80GS1000 raised the rear with a mono-shock conversion, but by far the most prevelant alternatives and consternation involve different means of extending front fork length. The stepped triple directly addresses this issue without having to seek out specific year forks (like 93 GSXR 1100).
So why it may not be obvious at first, the post is directly related to GSXR 17" wheel conversions.

It's actually a whole lot easier to installed GSXR wheels than doing full suspension swaps, I can argue that. This would be for a much bigger picture...those of us who want real suspensions. The new front wheel would just come with the suspension...unless you didn't want it for some reason.

Sorry to not be more clear, but ground clearance is the primary issue that relates stepped triples with 17" wheel conversions.

this thread makes me cry.

 

[makenzie71]

17" wheels just by themselves doesn't bother ride height...I have 17" wheels and lost less than an inch.

Duh

Duh

There is always the option of using a CBR 954 triple clamp set. The top clamp is stepped so you gain some clearance using it. GSXR750 forks fit the Honda clamps.

Any Ideas on the dimensions
for that drop triple?
What are the upper and low fork ID's
What is the offset (between fork and steering stem)
I Assume the fork separation is same as GSXR 750.

Another idea in the next post

There's a lot of dirtbikes out there with inverted forks with the same dimensions as the street bikes...has anyone thought to measure the length of the dirtbike tubes? Surely there's more to their increased length than just the legs...or I would think as much...

If your in a position where you haven't bought anything yet I highly recommend considering GSXR1100 forks. I'm using complete front end from 1994.

Yes I've lowered my ground clearance from 5" to 3.5" however the stiffer springs and reduced travel of the USD forks seems to take care of the issue. By the way I have a very big cooler and it also never comes close to the fender.

I've got 7000 miles of hilly new england roads on them now and haven't touched anything except my toe in hard turns. I wouldn't advise doing 20 mph over a speed bump but I can go over all but the highest of them at a crawl.

The more modern GSXR Showa forks are better than the mid to late 90's era KYB 1100 forks in terms of handling performance but you have to weigh that against the expense of solving the reduced clearance issue.
