Morning all, When fitting the 1199/1299 linkage to an 899, is the geometry altered at all when swapping the parts overs? Am I right in thinking that the push rod pick up points are the same for the SSSA and 899 so as long as the push rod is set at the correct length for F or P I’d be good to go? Thanks, Carl
I think you are right. Might be worth checking the ride height before fitting and after then compensate (if necessary) using the adjustable end of the shock.
Cheers Ian, that’s the way I was going to go about it. I’ve lined the two up side by side just now and and if there is a difference it’s very, very slight!
I won’t pretend that I have first hand knowledge of all of this and it’s a mod I’ve done recently to my 899. Info from a recent post has been shamelessly stolen from @LiveFast...... You don’t actually need the linkage that Ian is referring to - you can use the stock 899 one depending on your preferences. The stock 899/959 linkage is a none adjustable ‘progressive rate’ linkage. This basically means the as the spring compresses it progressively gets stiffer. Most people say for road use this is the better option as it gives a compliant ride but can also take a pillion. It’s a jack of all trades setup. The 1199/1299 linkage has 2 optional positions - progressive as the above and ‘flat rate’ this means the spring stiffness remains consistent throughout the full stroke of the shock. For track use and if you are on the sportier side of road riding and will never take a pillion, then most people prefer this option as it allows a more predictable and consistent shock setup. I have the 1299 linkage on my 959 set to flat as it’s a dedicated track bike. The spring weight on the stock 899 shock is 80Nm (possibly 78) - the stock 1199/1299 shock is 90Nm. This is because the swing-arm on the larger capacity bikes is longer and has more leverage. As Ian says you need to ensure the spring weight matches your riding weight in full kit. The spring fitted to the shock for sale above is 100nm so is very stiff in comparison to the stock 899. For the price you would be getting it for however it’s not a big deal to buy the right spring for your weight. "Rider Weight (In Gear) - Spring Rate 150 Lbs. - 75Nm 170 Lbs. - 80Nm 190 Lbs. - 85Nm 210 Lbs. - 90Nm 230 Lbs. - 95Nm 250 Lbs. - 100Nm Please note these recommendations are for the suspension in the FLAT RATE setting on the 1199/1299, or on an 899/959 with the adjustable linkage kit installed. For an 899/959 without the adjustable linkage OR an 1199/1299 with the suspension set in the PROGRESSIVE setting, chose one spring rate softer than normal recommendation. If your weight is between the ranges, you can choose either spring rate, choose the softer rate for less aggressive riding or the stiffer rate for more aggressive riding.
On my sssa conversation I fitted the 1199 rear link triangle with the p/f link bar. Set at progressive. Had to have another notch cut in threaded part of rod (see pics) as is wound out a fair way. I think due to longer swingarm and different mount points for rear triangular plate. My shock is the standard 899 one. This spring I’ll go to MCT to get it set up for my weight.
Much appreciated guys ... makes a bit more sense to me now .... gonna have a think on my 959 SSSA set up and see what I will benefit from most ..... thanks once again
You're in for a treat @Biot! Darren made my mates 899 a much nicer ride. It didn't deal well with a large, sudden bump before. Dave
Personally would not remove suspension to post. When you ride down, he waves his wand, and you ride home its a revelation. Done my 'r' Ohlins front and rear a treat. I know turn around is faster and cheaper if you post.
I think you have to book in advance for this. But you get to see someone who knows their stuff taking apart, stripping it down, and sharing a little knowledge to us suspension cavemen. If you do decide to post sussies off, he can fit part of rebuild at the end of a day, I think. So can fit in sooner than dedicating a specific day for you.
