looking for info on suspension mods

[monkey wrench]

hi, I'm looking for info on upgrading the suspension on a '09 street triple. the forks are confusing me the most. can I swap internals from speed triples or daytonas into the legs of a street(non r) with a minimum of modifications? it looked like I could swap the tubes but the internals look easier to come by and I don't have to swap the front brakes.

also, is the rear just a straight swap with an earlier model Daytona 675? if all this info is on the site, I could not find it.

thanks in advance for any help you can offer.

You can't swap the cartridges since the standards fork legs aren't machined for the compression adjusters.

The rear is a straight swap for any 675.

What are your forks not doing now? Mine actually worked fairly well after a few adjustments.

the thing they are not doing well is being adjustable. they are not awful in anyway, I just like the idea of being able to change some of the settings and experiment.

can speed triple fork tubes be used?

After riding a demo 675 R, I reallised the shortcoming of my standard version in terms of handling & brakes.
Took the bike to out local suspension guru, (does all the race bikes) who replaced the front shocks etc with cartridges from a CB 600RR & built me a rear shock with all the adjustments for the price a a new Ohlins shock. The difference on the track has been astounding, a bit hard on the road but it was a custom set up for track days. By far the best money I have spent on my bike.

Matris makes a set of drop in cartridges for the Standard Street triple that includes roller bearing pre-load adjusters on both legs and compression adjustment in one leg, with rebound adjustment in the other. Both on top so they drop right in the stock fork tubes. They will also customize the spring and valving rates to your needs. Comes complete, ready to install including fork oil.

Matris part # FT102S

They are not cheap but I have the high end Matris FO-5R cartridges for the R in my bike and find them to be better than the Ohlins, Traxxion, and modified OEM forks I have had on other bikes. PJ & Paige at PJsParts.com are US dealers for Matris and can help you with pricing. E-mail them and they will contact the factory directly for the best up to date pricing. A plus is that Paige also rides a Street Triple.

Is it a problem to swap the rear shock for a better shock (675 or st3R) and leave the forks as is on a 2008 non-R model? If the rear can be changed without changing forks, what rear upgrade do people recommend? Not sure why, but my suspension has become worse this year (only 13K on it).

some people have swapped out the rear shock for a Honda cbr600rr. better shock and much cheaper. do a search for cbr600rr shock.
