1290 Suspension

[yiloong]

Hi All, I just got myself a pair of Mupo Catridge kit and I wish to check with you the oil level / air gap for the cartridge assembly? Factory OEM spec is 110mm and the Mupo manual is 150mm. May I know which spec that I need to follow?

[kevxtx]

I would say you need to follow the instructions from Mupo Catridge kit.

Hi Kev, Thanks for your advise. Will follow the instruction from Mupo. Can't wait to see how the suspension perform...

[chrisRR]

Yeah I'm keen to know also. While the 1290 R is awesome for the most part, known issues aside, the front suspension is the biggest let down in my opinion.

I just assembled the Mupo cartridge into my forks and I encountered weird sound after installation. The sound like the spring hitting the center shaft.. anyone encountered issue before??

I have a reasonably simple question.
I don't want to put kits in or anything like that.
But I eventually will want to swap the fork springs and shock spring for a suitable item for my weight. Where do I get WP replacement springs or equivalent from? Preference is WP component but I would appreciate if I can contact a company give my weight, bike type etc and they send out the suitable replacement components?

Hi
I see some guys talk about fitting new suspension parts and asking advice etc...........
I think the best advice, leave it to a guy who knows what he is doing.............
I do many track days on a fireblade 09 abs (track only no lights etc), completely set up for track the only thing i changed was i got a 2012 rear suspension standard Honda fireblade it fits straight on the 09, better unit stronger springs then took to a professional. HM racing they know what there doing, been doing years, the blade was perfect 1st time for less than a £100 plus £200 for 2012 unit 2nd hand, nearly new. The bike was set up for me weight, sag and loved it 1st time not touched it since. So easy.........

When i bought my 2017 SDr for the road and last year and some track days this year are planed, after 1st service I took to HM racing and they set it up for road , what a difference feels planted on the road but after 2500 miles front feels a little soft will take it back and get them to check and change for for a few pounds saying best set up for track and road.........While I relax and have a coffee

What I say don't mess about with it unless you really understand it all................ for what it cost let someone who knows what there doing, no guessing, and if not quite right take it back till ok.
I know some like like to tinker but can be dangerous if not all balanced out with your weight and measured for sag etc
Just my thoughts.........

James is bang on. Let the professionals handle setting up your suspension. That said, the suspension on the 2017 is optimized for a riders weight of MAX 165-170 lbs. that’s what it’s sprung for. If you’re heavier (like me at 240lbs for instance) NO AMOUNT of adjustment will make this system work. You either need to replace the springs with heavier ones (like I’ve done with great success), or invest in a set of Mupo’s or w.h.y.

Either way, a proper suspension shop with then set up your bike properly for both the street and track.

It is absolutely the best money spent and the difference is night and day.

My $0.02

What do you think the upper limit is? At what weight would you change the spring?

[Mike690]

I’m about 200lbs and well over 6 foot tall. This bike is good for big guys in many ways but the suspension does need some attention for it to handle.

Mine has had heavier fork springs installed with a front revalve. The tuner also noted that the oil level in the fork was reduced as it was about twice the volume needed. The rear spring was Ok, tuner changed settings only and preload, so no revalve.

Bike has been transformed. I had been pushing the front way too deep into the available travel and had been bottoming out. The handling was not good prior to seeing the tuner, it was dangerous, most notably under power on long bumpy turns. This has now been fixed and it is a pleasure to ride.

Even if you are a lighter guy, a good suspension tuner can often make significant improvements. You may not have to pay as much to see gains as springs may not be necessary. What a tuner does is not witchcraft, but if you use a good one their knowledge is well worth paying for.

I'm 6'0, and 165 lbs no gear. Front end felt like it was gonna tuck all the time, suspension was soft up front. Went with the 5.0 n/mm front springs from RC8R. was much, much better on front.

Rear spring was OK for sag #numbers but I had to tighten up the compression considerably to settle it down. Had wobble under hard acceleration 1-4th gear and was pitching towards the rear a lot in corners when picking up throttle mid corner to exit.

I'm not a suspension guru but I know a bit, seems a lot of bikes are soft up front from the factory. My 2002 Hayabusa forks were a train wreck, went from .85 kg/mm to a 1.00 kg/mm and got proper valving. Completely changed the bike

[Spiff]

My last bike was a supermoto. I bought both front and rear from a track guy who happened to weigh the same (175). It transformed the bike. I could stuff that thing into a corner better than anything I've ever owned.

Now with the sdr I am all over the place. Reading what you guys are saying I have to agree the front is soft. I have almost tucked it, and while I stayed with it, I think both the abs and tc helped. My other issue is I am riding it like a supermoto, weighing the outside peg, and sitting upright. I need more feeling in the front if I am going to hang off it. Preload would be nice as well. I guess the moral of the story is I'm going to have to pay my buddy who owns a race shop.

Did you mess with valving?

Not yet, i think i just adjusted front clickers to firm it up a little bit. Would have to go check what settings are, can't remember. Can't rule out doing it in the future

Again, I wouldn't say I'm an expert at suspension but the stuff I have done has certainly helped calm the bike down and make it more stable. I actually wonder if sorting the off/on fueling of the bike with some Rottweiler stuff would help stability even more

This is strange? The spring on my 2015 SD shock has "170-185" printed on the spring.

KTECH will source what you need. Any good suspension shop can do the work.

If that chart # is kilograms of rider weight then the spring is appropriate for riders between 165 and 187 lbs. This suggests that the stock WP spring has the rider's weight printed in pounds on the spring rather than kilograms.
