One thing I don't understand about the #2-#3 shock is how it works without any means to increase preload for a passenger and extra load. I understand that they come with 4" of travel which is what has my attention but if the sag is set up properly for a solo rider and then you add a passenger and a week's worth of stuff it seems like you would lose a considerable amount of that precious 4" of shock travel in additional sag. Besides that, as the bike squats lower in the rear from the extra load the bike's attitude changes which effects suspension geometry, handling and ground clearance. I've had numerous sets of Ohlins on various different bikes over many years including the set I have on my GS currently and all of them have had some means of adjusting rear preload whether mechanical or hydraulic. I would have thought that adding a simple ramp adjuster or threaded collar wouldn't be that big of a deal otherwise it would seem like the choice of spring would have to be more of a compromise than necessary.

I currently have a set of Works Performance shocks on my SG/RG only because I didn't know Ohlins were available or I would have considered them. The WP probably don't have 4" of travel but they are very plush and have never bottomed solo or with my wife on board and a week's worth of load. They use an ingenious system of multiple springs and a lock out mechanism called ARS for adjusting spring strength. In my case the shocks are built with two springs per shock (you can get as many as three). One is shorter and lighter than the other and located on the top. The lighter spring handles small bumps and light loads while the heavier spring handles bigger bumps and heavier loads. This is a similar concept to progressively wound springs but the advantage here is that the wire size of the spring can be varied as well as the number of turns. The lock out mechanism determines at what point in the stroke the load is transferred from the light spring to the heavy spring. There are 4 positions. The system works flawlessly. There is a small lever built into the cast aluminum lock out that makes it a snap to adjust. You don't need an additional spanner or anything.

I can't comment on the quality of the WP vs the Ohlins since I don't know what goes into each shock regarding the dampening method used or the materials and tolerances utilized but I can say that the ride and handling with the WP shocks are far superior to the stock shocks as well as the high-end Progressive shocks I had before these. The owner of WP, Gilles Vaillancourt, has been a mover and shaker in the motorcycle suspension industry since the '60s having opened WP in 1973. He is also a member of the AMA Motorcycle Hall of Fame. The day I was there he was in the shop and supervised a spring mod I requested. I've recommended their shocks to two of my Harley riding buddies who have been very happy with them as well.

marcparnes please re-read my web site more carefully and the answers are there for your questions you have asked above.

FYI Wp are not sold in the US nor is there any support available that I know about in the USA. I have asked via e-Mail numerous questions and where to get information on repair of their products such as rebuild kits. I had customers requiring repair. I did not even get a reply to any e-Mails. This is not a company I really would like to do business with their customer service. I do not accept their products any longer for repair because there is no customer support. If you are living in the USA you are on your own. That is my experience on 3 different occasions.

If you went to last weeks AMA race in Thunderbolt Raceway, there was an Ohlins truck supporting their products. If you ride a HD and needed help with your Ohlins product, go to the truck and get it just like any Racer but you will have to wait until they have a free minute. If you have a problem with my product call any day and I will answer the phone unless I can not hear it, than I call you back on a missed call.

I am glad you are satisfied with their product and hope you are not living in the USA. We use progressively wound springs in some cases but if ir was up to me I only would use linear wound springs. Springs are for only holding the bike in a position (distance) in relation to the axle/swingarm. The spring is nutral other than that. Lesser quality and poorer quality shocks require the springs to be a helper or major part of the suspension. Ohlins only uses the shock internals for suspension. The springs only neutralize the load.

If you set up your bike (for instance) for single 100% up and weigh 180 lbs than put a 350 lb passenger than you got problems. A 135 lbs, no problem. Going on a 4,000 mile trip & adding 70 lbs, add pre-load.

Hi Howard,
I was speaking of Works Performance not White Power. Sorry for the confusion. BTW, I'm a big Ohlins fan and have been for many years. Is it not possible to include a way to easily adjust preload on the #2 shocks?

2 included spanner wrenches. 3 clicks on a ramp. We changed over recently with a preset pre-load than a snap ring with groves to avoid confusion. We use to have a threaded body and a need to set the bike up with the different sag #s. You know from the racing days. With doing this lots, we just to it into the range than gave them 3 choices. If it goes beyond that than a spring & valving change may be necessary to keep the units so plush and within a sweet spot.

If any of you are sweet on a 350 pounder you will need to purchase a spring compressor and a set of different springs or buy a #3 that still has a threaded body, the weight is just too much difference to overcome.

A hydraulic pre-load adjustor can be ordered but I do not think it would fit within the confines of the hard bags or for sure leather (Classic) bags. A remote hydraulic adjuster is not made for a 36 mm body like the 46 mm type.
