switching to progressive coil over rear shocks

Post by roadwanderer2 »



i've been thinking about changing the rear shocks on my SEi going from air to progressive 412 coil-over manual adjustable rear shocks. anyone have any opinions, pros or cons about them?

Stuart - have replaced the rear air shocks on my '85 LTD with progressive shocks. Parts are:

Progressive suspension rear shocks 1200 - 76-1206B
Progressive suspension rear shock springs - 76-1364B

The ride and performance is extremely good both one and two up. I have them set on the 4th preload adjustment at all times. The only issue (quite minor) is that these are slightly longer than the air shocks and when the bike is on the centre stand the rear wheel is still on the ground. To compensate for this I will put a 1/4 to 1/2 inch piece of plywood under the centre stand. I only do this when I have to such as when I am working on the bike, otherwise I use the side stand. You do have to remove the saddlebags to adjust the preload.

As an aside, just put new Michelin Commander II tires front and rear on. Use Ride-On Tire Balancer and Sealant - 8oz in the front and rear tires. Was using Counter Act beads but prefer the Ride-On product. Check out the you tube regarding this product, it is impressive. No more ugly silver weights on the bike wheels.

Cheers

hey Ernest, all this information is good to know, but 2 questions.......did you install the standard or heavy duty shocks, and with the shocks set on number 4, how does your bike ride.

Stuart - out and about on the bike this morning, will get back to you. Have received an answer from the company in the UK that has shocks for our bikesand may be an alternative to the Progressive shock. Will get you this information as well. Their web sit is www.bitzforbikes.com.

Bike rides quite well with the preload on the 4th adjustment. Don't have to change when I ride dual.

Cheers

now see, thats the information i was looking for. i want to be able to set the preload and be comfortable whether im riding one or 2 up. as for that site you gave me the link to, i can't find anything for the rear shocks be them for the 85 or the 86 1200. BTW, i meant to ask you, did you get the standard or heavy duty shocks.
