Hello all,
The only problem I have had with my RT-S is the rear shock absorber. It lost all damping on the first day - I rang Dealer and it was replaced that afternoon.
The bike ran trouble free for 4,500 Kilometers and the Shock failed again. rang Dealer and it was replaced the next day.
I have not read of any others with rear shock problems, but I hope, from my eperience, that BRP look to their supplier for a fix.

Anyone had this same problem.
Regards
Bob

Was the issue that you were loosing the "air" on the rear shock ?

I had an RT-S out for the day and we heard the air compressor blowing off alot ( hissing ). Not sure if that's normal and I to wonder if youn lost air pressure or dampening.

Yes it is normal to hear "air release" from the RT-S when running. :)

I agree, Mine is set at 70psi I hear the hiss sound when it is adjusting I don't think it is escaping.

It is not the Air Bag.
The Airbag is seperate to the Shock and sits in front of the Shock.

When the shock was removed and compared to the new one it had lost all of its compression and rebound damping. My Dealer replaced it no problem.

When you push down on the rear suspension hard (stand on the rear foot rests) and release, the machine should return up to the original height in a slightly slowed speed which is controlled by the rebound damping in the shock.
If however, it returnes quickly and there is a audible clunk at it gets to the top of its travel your shock needs to be replaced. It is a sealed unit and cannot be repaired, save for suspension specialists who can cut them open and perform magic and close them up again. These shocks are not expensive enough to warrant repair so they are just replaced.

I have had two fail now and I wonder how long until the next one goes. I did read the brand name but cannot remember, all I can remember is they were made in Mexico. BRP should approach their supplier for a fix IMHO.

I'm glad I didn't order the RT-S, I went with the RT a/c. The whole "air-shock" thing made me nervous.

Just so ya know, all of the RT models have the air ride suspension, the difference is the RT-S has the onboard compressor, where as the RT and RT/AC use the Schrader valve (located under the seat on all RT models) that you fill/release the pressure manually. :)

I'm familiar with how the air ride works on the RT-S, I have one. ;-)

I just find it strange after having two Spyders, I have not seen the issue you are having with the rear shock, something does not appear to be right. :TgC_emoticon142:

From Arthur---Mexico City
I installed Corbin sidecases on my 2008 SE5 Spy. The right sidecase's mounting lowered the muffler so low that it was rubbing against every bump on the street and we have lots of bumps down here. So I machined 2 supports that raised my Spy .800" where the rear shock is and that cured my problem. What I did was lengthen the shock jacking up the rear of the Spy. I did this because I didn't want to change the "ride", only the height.

I'm pretty sure I have the rear shock problem. Several weeks ago I had a small oil spot on the floor, couldn't find any leak. After reading this thread I went out a checked mine by standing on the passenger's foot board and jumping off. The thing bounces like a basketball! Now I think that oil spot was what was left of the oil in the shock. I'm waiting on a return call from my dealer right now to see if they have one in stock. Thanks for the heads up on this. I think it's part of the handling problems that I'm having.

Just drove me new RT home last nite from my dealer, 24 mile away and I did hear a metalic sound when hit bumps. I did not know the rear suspension was Air assist but I did notice a brass valve under the side cover when checking the oil. I must read my manual, ha ha. Something people don't do. I did ask for front and rear adjustments set to hard for 2 up riding and did not know or was not told I could add air to the rear suspension. Thanks for the info. :)

The brass fitting under the side cover is for adjusting the headlights. The Shrader valve for the suspension is under the seat, right side toward the rear. The RTS version also has a button adjustment on the dash for ride height.

I had my dealer service guy check my shock while I had it in for an oil change. He said he would order me a new shock as it was obvious that it wasn't working. A short time later he told me the tech thought it was the air system. When he took it on a test ride he put 60psi in the air bag, when he got back it only had 30 psi in it. As politely as I could, I explained to him that the shop manual shows the air system to be completely seperated from the shock. Even if it is broken (it is) it doesn't have any effect on shock dampening. He said he didn't think I needed a new shock, I asked him to order it anyway. He is supposed to talk to BRP Tuesday, hopefully he talks to someone with enough tech savvy to explain he needs to fix both problems! The test for a bad rear shock is easy, instead of standing on the passenger peg I just pushed down on the passenger handrest and then let go, even the wife noticied the bang when the shock topped out.

Yep. I took a fast look at that adjuster umder the side cover and thought it was the air adjustment for the rear shock. I woke up and looked in the manual and wouldn't you know it, it was under the seat, ha ha. I still get a loud metalic sound if I go over a big bump in the road but not over small ones. I will get it checked out at the first inspection. I was out for a short run today and it was windy. I did get tossed about. I am waiting for the RT sway bar from Evolutione and think that will help on windy rides. I will increase front tire pressure as well, maybe to 20 psi. I found that setup on my RS to work the best, time will tell. Till later. :)

Scotty. Just read about your Problems with your RT-S. What did you mean about Handling Problems? Can you explain Please, Tony

It appears that mine is bas as well. I only have 1500 miles on my RT-S and noticed the clunk on the last two rides.

Just an update here on my handling of my RT base model. First, I'll try to change my statis for receiving private messages, Sorry Scotty.
I did have some problems with stability and after a few days it came to a head. Problem!!! Rear Shock holding pressure. I asked for my new Spyder to be set up for 2 up riding and stiff settings. I did check the rear air the next morning (73 psi) after receiving delivery because I did not know that I had rear air shocks like the RTS. I now wish I didn't. Only 5 days after delivery and 14.5 psi. That is what was affecting my handling. I now check it daily. Last night it was 65psi and this morning it was 44.5 psi. I know I will get it fixed but it sounds like a lot of guys are having this problem. Sounds like a manufacturing fault I hope, not a design fault ???
Another thing about the rear shock, Yes the rear does bounce up and down like a dampening problem with little air (14.5 psi) in the rear shock but as soon as it is topped up that goes away. Seems like the air pressure does all the work. I do not notice any up and down bounce while riding 1 or 2 up as long as my rear air pressure is correct.
Now about the handling of my base RT with 17 psi in the front tires, front shocks set max setting on spring purches and 70 psi in rear air shock. I took my Spyder out on the HWY, something I did not do on the DEMO either and this is what I found. One up riding at 60 mph was OK. I took it to 70 and the same. Remember I am still breaking in here so I only went up and down. I felt comfortable enough to do some passing. 70 mph to 85 mph and still pretty good. This RT is NOT an RS like my first Spyder (2277) It doesn't seem to whip up or should I say be as light footed and spirited as my RS. I am happy with the comforts of the RT because my Wife likes the rear seat much better.
So as soon as I get the rear air shock repaired I will get use to driving differently with my RT because my Wife likes it. I to am more comfortable but will miss the sportiness of my RT. :)
