NMN Riser & Corbin installs

[Firefly]

Installed my Corbin seats & backrest today - along with the NMN 3" risers.

The seat:

Install was very straight forward, but one of the front welded bolts that is used for the handrails was broken - as in the weld holding the bolt to the frame busted off. Had to tear more of the bike apart - remove the unwelded bolt and replace with nylon lined one (stole if from the stock seat shock).

The Corbin fit is great, feels great - looks great. Still trying to get used to having a backrest. Makes getting off and on the Spyder a bit different!

The seat feels great when riding, but might have me sitting a bit more forward - and for sure is more slippery!

The quality seems really good, but I was a bit shocked at how the bottom of the seats look. Not a nice finish - just looks really rough - like not finished. I know that's being picky, but heck - the two piece seat and backrest was $800 !

Also one small thing that irks me - they tell you to use Loctite when installing - but don't provide it. Okay, sure - Loctite is cheap - and I already have some - but it's a nice touch when it comes with the product. The NMN risers came with Loctite - and they were only $200!

__________________________

NMN risers :

Install was trickier than I thought it would be. Main issue is getting in and cutting zip ties to free those cables up. The reverse one seems to be the tightest. I have the 1" BRP riser, so went with the 3" NMN risers - and it is VERY obvious that you could NOT use their 4" if you have the BRP riser. No way will that reverse cable reach.

Install went pretty good, but the directions were somewhat lacking. Nowhere in them, or out here did I see any mention of allen set screw in the bottom of the riser brackets. Didn't know if they wanted it tightened first or second, loctite? I winged it and it seems fine - used loctite.

I re-routed the reverse cable a bit to have more room.

I got the black anodized version - and man are they SHARP looking! The black doesn't stand out as much as the others - blends in nice and really looks like a factory part of the Spyder!

First ride was really strange! I had them pretty far back - rode for an hour and it just didn't feel right. My palms felt like there was a lot of pressure on them - like I was wedged between the Corbin backrest and the bars.

Went back to shop and made a change - forward this time. Still felt strange, but in a different way that before. Went back and found a spot in the middle that feels pretty good - not too much pressure on my palms, etc. Nice to have the option to adjust. Does anyone know if there are any 'standard' riding postures to look for when adjusting these?

The Spyder handles VERY differently with these on. It was like the first day I had the Spyder all over again - learning to ride from scratch. Turning is easier and response seems quicker. You're really at a different angle and if you turn using the same forces as before - you'll oversteer.

Overall I think I'm really gonna like these - just have to get used to them now - nothing a few hours of riding won't cure I'm sure.

Took some twisties at 80 and nothing fell apart - but you can bet that the thought going through my mind was : Did I tighten that bolt? If that came off - it would be ugly!

One thing - does anyone know how to attach the upper bolt covers? They look sharp - just not sure best way to attach them.

So far I would highly recommend both the Corbin and NMN risers.

Use some clear RTV silicone adhesive, a dab will do ya.

Good eye we will have to add a line about tightening the allen set screw last. :thumbup:

Well, today I had quite the day of riding - much of it really bad - in fact - the worst day of riding I've ever had on my Spyder.

I had ridden last night after putting all this on, made a few adjustments to the risers and finally decided on a good middle point - or so I thought.

Today I take off for a ride with my new NMN risers, Corbin seat & backrest. 20 minutes into the ride my hands are killing me - both are asleep. It got so bad I had to pull over and rest them before heading back home. I was literally thinking what did I do to my Spyder? All I wanted was my old Spyder back.

A stop at Mom's for Easter dinner took my mind of things for a bit - but then I got the tools out and started looking at everything.

One thing I should not have done was install both the new seat and the risers at the same time. Should have done one and then went for a ride, then do the other. That is usually how I do things, but this time I just knew I wanted and needed all these items.

The other mistake I made was not testing the risers on the road before cutting the bars off .

What I found was that with the Corbin backrest installed, it makes me feel like I'm pressing between the bars and the backrest - and I don't think the spacing is right - at least not for me.

I made an adjustment to the risers - moved a bit closer to rider - and removed the backrest and went for a long ride. I took tools with so I could adjust the risers if needed. I did stop once and make a minor adjustment.

Things were MUCH better. I think the backrest really caused problems for me - perhaps making me sit too far forward. So if I stick with the Corbin, I think it will be sans rider backrest.

The NMN risers look really sharp and I'm getting used to the new position, but the handlebar vibration is far worse now than before. I'm pretty sensitive to hand vibrations, and had done work to my stock bar to get rid of the vibrations - but now they're back.

My stock bar had a Bar Snake installed, throttlemeister heavy ends and nice foam grip covers. That combination made a huge difference.

The part of the stock bar left on the bike still has the Bar Snake inside, I have the same grips and covers along with the same Throttlemeister end parts. So now I'm left wondering what else I can do to tame down the vibrations. I know many of you out here said your bar vibrations were reduced by installing these risers, but mine has increased.

One thing that struck me as a bit odd is that when the new NMN bars are put into the riser brackets, there is quite a bit of play to them. The fit wasn't that tight, but of course since the large bolt holds them in place, they are tight and not moving around or anything.

Did anyone else find that same semi- loose fitting of the bar ends? Just wondering if this could be related to the vibrations I'm having?

I'm open to ideas on how to reduce this vibration as I really don't want to get new stock bars and remove all of this.

So here are my findings and problems I need to resolve.

1. Corbin seat pushes you further forward. Not sure if this will turn out to work as is or not.

2. Corbin seat is MUCH more slippery and you tend to slide forward when stopping.

3. Corbin backrest is too far forward and just isn't going to work.

4. NMN riser install somehow increased my vibrations - need to figure out some way to reduce again.


TIA !

Did you use the 3 inch on top of the 1 inch BRP riser?

I need to raise mine up some. Thanks for the info.

Yup - 3" ontop of BRP 1".

TIA !

I had this trouble when we first installed my corbin seat. The first right turn I almost slid off the thing. Mine seems to be getting broke in now and I don't have that problem as much anymore. I probably have about 300 miles on the seat so far. Hopefully yours will improve soon.

You are aware that the Corbin backrest is somewhat adjustable, right?

Yup - I know it's adjustable - but that is just the angle adjustment. It really feels like it needs to be back 1-2". I might just not like the way it makes me feel 'locked' in between the bars and the backrest. Like I feel my back has to be up against the rest, so I have my arms tighter to push my back against the rest. I now remember last year I tried a bag for a backrest and had a similar feeling, but I think I was able to move it back further and it helped.

I'm thinking maybe I should have got the smuggler trunk with just the bump pad. I hope to run into someone that has it and try it out.

The seat is really nice and I think with time I'll like it even more.

My question fits this thread (I think) but not addressed yet.
I am going to install CORBIN Bags and was wondering how complicated it might be. It is pretty straightforward? How long would it take (approx) to do. I have the stock pipe on the Spyder. How many hours should I expect to have it installed at the dealers, how many to do it myself. Anyone done thiers themself?

Took me about 2 hours to the bags.:doorag:

Years ago when riding my Goldwing, several of our riders had installed backrests. I sat on one and I didn't like it. Having the feeling in my back made me feel caged. I have never had one, though many people love them. Not being an aggressive driver, I have never noticed the Corbin seat being slippery. May be the leather print I used. I went with the elephant skin print. Have now had it almost 5000 miles and we love it.

Do you feel you're sitting more forward on the Corbin?

I think the seat will work out fine - my bigger concern right now is the handlebar vibration I now have with the risers. Gonna have to try some new gel grips or something.

I got to wonder how everyone else including me has less vibration and so far you're the only one I've heard of that has more. The riser and the bar itself acts like a bar weight so I can't see how this is possible. :dontknow:

Well, with my weight, 140, there's a lot of Corbin to move around on, so I have a problem with staying against the back to begin with.hyea:

With over 400 sets now on the street, this is the first time I have heard this myself? :dontknow:

I have the Corbin seat, a nice backrest I got on eBay (for $80!), and the 4" NMN risers. I weigh about 114 lbs.

I don't find the seat slippery at all and was surprised to hear this. I've only put a couple hundred miles on the new seat, but it's wonderful for me!

I love my backrest too and don't feel boxed in at all. I love having something to lean against!

I don't notice any vibration at all with the risers, so was surprised to learn you are having problems. The NMN risers allow me to sit more upright, putting much less pressure on my hands and wrists, making my ride much more comfortable. Plus I think they look great on the Spyder!

Guess none of this information will help you solve your problems! Just thought I'd post my experience. Hope you get things set up so you are more comfortable!

Sorry, I didn't mean to make it sound like the NMN risers were the CAUSE of the vibrations. I'll try to explain better.

I don't think it's the risers causing the vibration, and certainly they may reduce the vibration as compared to the STOCK bar setup. I had modified my stock bars to reduce the vibrations, so my vibrations were reduced to almost none. Been too long since I did the mods, so I can't remember what they were like before.

I'm not saying the risers don't generally reduce vibrations, just saying in my case it feels like there are more vibrations than what I had before. Perhaps it's a frequency thing that I need to work out. I do have more noise than many because of the race airflow setup.

The vibration was a problem I tackled before, and will again. I have carpal tunnel problems in both hands - so I'm very sensative to vibrations. I also had finished doing all the installs (using my hands a lot), so that might have made my hands more sensative right away.

The other thing is I might not quite have the right angle or posture. Removing the backrest has helped. With the backrest in place I felt like I was pushing on the bars to keep my back against the rest - and perhaps that added pressure is what made my hands fall asleep.

I really DO like the risers, just need to tweak some things - maybe add some gel grips or something. The black finish really looks sharp - most wouldn't notice they were not factory parts!

You'd like these grips!
