Progressive Suspension

Post by Rednaxs60 » Thu Aug 02, 2018 5:15 pm



Have perused this and the other GW forums for information on upgrading the suspension on my '95 GL1500 SE CDN Edition. Seems the upgrade of choice are the front fork springs and rear 416 series air shocks from Progressive Suspensions.

My reasons for doing the suspension upgrade is that I consider the suspension a safety issue, as well as a quality of ride and performance issue. The suspension is the only item on the bike that keeps the tires firmly planted on the road and allows for quick adjustments to changing road terrain. I agree with WingAdmin's thoughts on the two different types of rear shocks and how each interacts as a system. This is much like the front forks on an 1800 where each fork does a different job.

My dilemma is which 416 series shocks can be used. Sent an email to Progressive querying what it has to offer. My email text was: "Have recently purchased subject motorcycle and want to upgrade the suspension. I have perused your site and it indicates that the 416 series shocks needed are the 416-1633GLA and the front fork springs are the 11-1152. Can you confirm that this is what would be needed."

The reply from a fellow named Chad in company service/warranty tech was: "I cannot confirm. We have not had that bike in to test fit. Those part #’s are for a stock GL 1500."

I have checked the weight difference between the '95 Aspencade and the '95 SE and the dry weight is within 12 Kg - SE being slightly heavier.

Having mentioned all the above, can anyone chime in with some P/Ns that they have used and possibly an opinion on what I have mentioned.

Cheers

Did some more perusing of the various forums including this one. Looked at the thread by WingAdmin: viewtopic.php?f=14&t=37869 His bike is a 2000 SE so it should be close to what I have in weight and such.

Noticed in his pictures that he still has the Progressive sticker on the Progressive shock 4161633. I speculate that the 4161633 GLA rear air shock will do the trick. Interesting how you find information. This is the rear air shock recommended on the Progressive site for a 1500.

Cheers

You got it. Chad apparently needs some training. The 416 you mentioned is the correct part number for all GL1500's.

Received the 416 shocks last week.

Got the front forks rebuilt and installed new Progressive springs. Has made a significant difference in the ride quality and handling. The bike came with a Superbrace installed so I will nit be looking for another. Used Belray 15 wt oil. May try a 10 wt next. Have you tried a different weight oil since install of Progressive springs in your 2000 front forks?

Planning on install next week for the 416 rear shocks along with drive train lube and air dryer desiccant refresh.

Cheers
