If you measure your stock shocks at rest (or just laying on the floor) are they 10" or 10.5" ?
I'll measure them tonight and let you know.
I used the VS800 Intruder in
Progressive's application finder
. For the 412 series shocks, they list the following:
Standard 11"
412-4233C
Standard 11.5"
412-4201C
Standard 12"
412-4228C
Standard 12.5"
412-4207C
Heavy Duty 11.5"
412-4236C
Heavy Duty 12"
412-4238C
Heavy Duty 12.5"
412-4214C
The last is the set I bought.

What is the travel on these shocks versus the stock ones?
I'd like more travel with the same load over that distance. Not just taller or stiffer, but taller and the same load rating. Thereby, a more cushioned ride without bottoming. Is that what we are talking about?
Thanks.

Mine are the 13.5" model, and I think they have about 1.5" more travel than the stock units.
Remember that the shocks sit at about a 45 deg angle, so for every inch of shock length there will be 1/2" of lift in the rear of the bike.

That is it - eliminate the bottom out of the stock shocks which happens quite a bit and sends the impact to the seat.
It takes a much higher load on these progressive shocks/springs for the last inch of travel so even with the same length bottom out is less likely.
In reading the stats on these models they seem to be the same shock body ~11" with ~2" of travel and every inch over 11 adds about an inch.
Lancer - the lift is going to be more than that, in all these models the initial compression of the shock due to the weight of the bike and the rider is less because of the stiffer spring.

Okay, I measured one this morning and it was 10.5" eye-to-eye (center-to-center, to be specific). They were still set at the highest preset also. At rest, I don't think it should matter because I'm thinking they should be fully extended no matter which preset but I thought I'd mention it anyway.

I was refering to the "unloaded" height of the bikes rear when a different length shock is installed.

Just thought I'd mention: I did need to add a 2x4 to the side of the homemade lift/stand for it to be able to function again.
While it's obvious that the increase in height puts the engine at a forward tilt, I thought it pertinent to state that the new angle also changes the oil level sightglass' position noticeably. I'm not really sure how much of a difference it makes but it's worth noting. I used the lift to make the bike more level to check the oil level. Has anyone else with higher shocks noticed this?

Hi Rob;
I can't help but think your bike is too high in the rear with those extended shocks, especially if it effects your sight glass. I see you opted for the heavy duty springs as well. Do you see that as a good choice? Can you adjust for sag with the shocks in the softest setting? How many preload settings are there on the Progressive shocks and what setting do you find best? If you set them to the stiffest position does the rear wheel chatter when brake skidding the rear tire? Like yourself Rob I too am looking to upgrade my suspension and any help you can provide would be super.

That is one deadly looking bike, Savage_Rob. I can see a bit of the Kawa klr in it...you know, I just spent a whole mess of time friggin' around to get the seat higher and that's probably what I should have been doing from the get go-I know my shocks are gone, anyway.
My bike with the higher seat is more comfortable for me but I just don't like the feel; it's almost as if I'm riding up on top of the bike now instead of IN it, if you know what I mean.

Been on the fence too long on this one - I'm going to toss a coin and order in the 11" shocks today - looking for about the stock rear height - either model 412-4233c (115/155lb) or leaning toward the 412-4232c (90/130lb) both have the same travel and the 90lbs is about stock spring strength and 130lb should slow it down before bottom.

I hadn't really noticed but I'm glad you mentioned it. My driveway is inclined some & I probably ought to check the sight glass with the bike pointed up the incline now with the 12.5" Progressives. I always checked it in the garage where it's flat. I need to get one of those long stem mirrors too 'cause I hold the right grip & lean down to look while trying to keep it verticle & nearly drop it half the time.

Say Reelthing, let us know how the new shocks work for you when you get them mounted. It sounds like the 90/130 spring rate is the closest match for a Savage offered by Progressive. Do you use a 140/90 15 rear tire and do you currently have any tire interference problems?

Ok ordered the 90/130 shocks - the rear tire is 140/80 metz 880 - no clearence problems - I'd like to stuff a 150/80 but the wheel width is below the minimum spec for a 150mm tire

I think there are five settings; I don't remember. I have mine on the lowest/softest preset. The regular shocks would probably be just fine. I just figured that being 200 lbs, the heavy duty couldn't hurt. They are probably a tad stiiffer but I don't have another set to compare them to. I got the 12.5" set since Babbalou had done so well with his. I actually like the extra clearance but do need to alter the incline to check the oil. If I were doing it over, I'd probably opt for the 11" or 11.5" versions. I knew my stockers were 10.5" and I figured a 2" longer shock might raise the rear of the bike 1" or 1.5" at most. It's weird how simple geometry didn't seem to apply though and 2" at an angle raised the bike by almost 4".
