Rear Shock for 1100 Evo?

[koko64]

I know there is a budget Ohlins that is "OK". What about this one? I've seen a very fancy Wilbers shock with high and low speed adjustment too. The oem Sachs shock falls through the initial spring rate too quick and then gets bloody harsh real fast as it reaches the fat guy/pillion rate. I'm 200 without gear and its harsh. I backed off the preload and damping a little and caused other issues of course because the spring is just wrong. I can get a used oem Sachs for a little over a hundred bucks and see if my suspension bloke can skim down a Showa valve for it. Dave at Kroozetune Melbourne rebuilds and modifies the unrebuildable, but he hates these shocks. If only it was a Showa.The basic Ohlins which people spring for is around 800-900 bucks here. When Dave's shop reopens at the cessation of stage 4 lockdown, I'll ask whether a spring change will do a half ok job. I have a spring bank to raid in the hope that the correct spring will bring the shock close to the performance of a basic emulsion type Ohlins for a couple of hours of my time.

Well, my local shop has ceased working on street bikes and now only builds their own parts. They were good too.

I'm talking to local people looking for a solution and was also recommended Dan Kyle's shop by Moronic. That is an option.

I still have a lead on a low mileage oem shock that could be tuned and resprung. The issue with the oem shock is harshness in high speed compression damping (sharp edged bumps). The lower speed compression damping and rebound feel quite good. The shock is well controlled over most bumps and dips, just harsh at times.

Any thoughts?

Such a nice bike - GET IT SORTED  a mid price shock that can be serviced and later sold locally'ish.

[koko64]

The bike is well tuned, the forks and ergos are done, just the shock and mid pipe to do.
It's exciting to ride.

I have rediscovered a suspension guy from my racing days who is still working and very accomplished. I thought he had retired. He is a fan of the direct link suspension on the Evo and most importantly understands and has data re Ducati suspensions.

A spring, service and revalve will come in at half price of the basic Ohlins (including the cost of providing a low mileage spare shock).

With the Pacific Peso plummeting in value, taxes and shipping costs, I'm happy with this deal.

Spoke to my suspension bloke today. He said that the oem dual rate spring is too soft then nearly doubles its rate with all the ensuing consequences. The shock initially falls through the stroke unweighting the front (yay), then hits a wall going all hardtail and losing rear traction. What more could you want?  An Ohlins linear spring and revalve are in process.

Should get it back next week. Now to select a method of suspending the bike safely. The rearset bosses under the cases look like they should take the Ducati style under engine stand or a scissor lift. Anyone tried this?

[Howie]

Ducati progressive springs at work again!

[koko64]

Howie, how would you suspend the bike? I'm a little leary of the vacuurial case design

[Howie]

Um...are you asking me how I would support it while removing the shock?

[koko64]

Yeah, I have both a scissor lift and Ducati under engine stand. The scissor lift will lift from the rearset boss on each side of the case that supports the rearset. The stand uses the similar boss with its pin. I don't think I could be stuffed removing the rear sets. 

[Howie]

I can tell you what I did with my fire generation Monster.  Raise the bike with the rear stand.  Long steel rod through the swing arm pivot stand,  Lower onto automotive jack stands.  I have no idea if that would work on your EVO.  An option that works on many bikes is raise the bike on a rear stand, bike under a ladder.  Strap bike to ladder.

Just serviced suspension on the MTS:
Under engine stand til rear wheel in the air, then a plank under wheel til sweet spot of
no pressure of shock bolts is achieved. Bit fiddly but do work.

Thanks to you both

When I swapped out the rear shock on my 796, I used my rear axle stand, then put a piece of plywood under the motor, and then jacked it with a floor jack to unload the rear shock.  I drilled a hole for the oil plug to set into.  It was a little wobbly, and I likely set something on either side of the front forks to steady it, but it was a fairly quick job after that.

[koko64]

Cheers.
That's reassuring as I'm going to use a scissor lift on the rearset bosses once the bike is raised with the rear stand to do just that. The later cases are thinner so Im glad it worked out.

The lift is like this.
