Stretch The Front

No, not a frame stretch jsut a +2 fork stretch.

I have a plain jane 92' FXR but I would like to get her up to the SP +2 height and improve the suspension. The back end is really easy, jsut buy the shocks. The front end a bit more complicated. I have 4 pot PM calibers that do a fine job of stopping the bike. The lowers have been powered and look great. So I have no interest in swapping in an SP front end or even going to an FXDX front end.

Is it possible to purchase the +2 tubes (45393-87 is active and available) build them with progressive springs, speed merchant pre-loaders, and a fork seal kit and just slide them into my bike?

What other parts would I need? Dampner tube?

Cheapest way to do it would be to swap out the stanchions and add 2-in spacers to the springs.

Correct way to do it would be to swap the stanchions, springs and dampeners.

Ad a set of custom springs and convert it to emulators and you'll have an improvement in ride and control.

Note: OEM tall springs are built to have air on them for anti dive. So they tend to be real mushy without the air system. They ain't great with a working air system.

The tubes are still available for under 200 a set, progressive or works springs about 100, I picked up a set of new preload adjusters for 80. Are the dampner rods different from my current stock setup to the +2?

Im heavyweight at 275 without gear and I have to cover a few miles of dirt road before I get to the endless miles of crappy two lane country roads (so much fun)...do you think the progressive sd, progressive hd, Race Tech, Traxxion or something else?

Do you like the Race Tech Gold Valve Cartridge Emulators or the Ricor Intiminators better?

As a rule, dampners are matched to springs, by part number. So you need to sit down with a parts book to see what goes with what.

The dampeners very in length, so they effect the installed height of the spring. Or, long dampeners go with shorter springs and visa versa.

And the dampener is also used to set the travel limit.


As for post counts, they don't really mean much. Just a reflection of the number of posts people make. There are people around here with thousands of posts, and hardly any of them about scooters.

I put Progressive fork springs on my '92 FXRS- same front end as yours- and loved them so much that I put their 412 shocks on a few months later. The difference over OEM is amazing. The ride is taut and supple, not soft or springy. They've got 85,000 plus miles on them now and I'm still just as happy with them. I did have to crank up the shocks (standard, not heavy duty ) to the second notch after several years. So you might want to consider whether you need taller suspension on the front, or just better. Keep in mind, though, that I weigh over a hundred pounds less than you. But I carry saddlebags and a tour trunk at all times they probably weigh over fifty pounds with all the tools, cable lock, quart of oil, etc, in them.
