Anyone buy the Ohlin's race kit for the R1M? I haven't removed the front fork springs yet on this bike to see exactly what spring rates are in these forks since the service manual specs are incorrect. I hope they are marked!
Anyhow I contacted Ohlin's who mentioned these are essentially the FGK 235 forks internals with electronic servos.
I got a quote to upgrade the rear shock with a ride height, hydraulic preload adjuster and a heavier rear spring but I can't determine what fork springs are in this thing and the Ohlin's folks think they are 1.0. Anyone know for certain?
Anyone purchase different springs for the forks and if so what spring rate and what's your weight without gear?
I want to do a few track days next year and want to get the suspension somewhat set for my weight. My riding style is aggressive since I did 7 years as an AMA pro.
Just looking for others opinions here since suspension should be the first item of business for doing track days.......at least safely anyhow. :grin2:
There was another discussion about the spring rates and the figures quoted in the manual. That figure is for both forks so it makes them a bit over 1.0

Yes...bought and installed by Markbilt in NJ. Changed springs up front, ride height adjuster for rear and changed the spring rate up by one spring rate. The difference is substantial and it is the difference between riding a well set up street bike versus a well set up race bike.
Turn in much better, communication with the front tire and rear tire is much better.
Thanks for the reply;do you know what the front spring rates are they installed? What's your weight without gear?
I know I'm going to a 95 rear spring but I'm on the fence for the front and I want to get it right the first time.
What's confusing is the manual claims both springs combined are 2.14 so that is 1.07 per leg. Ohlins wants to sell me 1.025 or 1.05 so something seems off and the front springs feel soft for 1.07. Both springs Ohlins is offering are lighter springs.
Ah, yes...thanks for that so the springs in the front of the R1M are comparable to 1.0 N/MM Ohlins springs.
I just want to make damn sure I don't have to purchase two sets of springs and guess at the correct rate. I'm going to do a baseline on the stock springs free and static sag once I get a chance and go from there.
So what's the recommendation for fork springs for the M with a 200 lb rider (with gear) with advanced riding skills? I'm going to install the Ohlin's race kit spacers in the forks and go to a heavier spring just not sure which one.
Spring part numbers I think are the same as the FGK235 inserts and the part number starts with 08790-xx I do believe?
I havent found anyone that sells just fork springs. The stock springs are 1.0 in the forks. Waay too stiff for me at 190. I like it a little under-sprung for the front anyways as I think it provides better feedback. The rear I run a .95 spring which is pretty stiff for my liking also.
I am looking to replace the springs and having my suspension guy hunt some down this week. Race-Tech doesnt list the 2015 model yet on their site. Dan Kyle (Ohlins) also doesnt list just springs yet. I havent called anyone yet, and hopefully they just havent posted them to the sites yet.
Anyone know if you have to drain the oil to replace springs? I know this varies depending on the bike.
You don't have to but, it is really recommended. It is a quick and easy opportunity at that time to put in fresh fork oil and ensure the oil levels are correct and even. When pulling the springs you will inevitably lose some oil. Try calling Jon at CTR Suspensions (865) 579-1161 I'm sure he can help you out.
Anyone install the Ohlins front fork spacers from the race kit? If so did you have any problems with the the spacers making a shit ton of friction noise in the forks when pushing on the front end?
The Ohlins taller spacers don't have a saddle for the front springs to sit in and sounds like the spacers are rubbing against the inside of the fork leg? Anyone else experience this if you installed the kit? Guess I'll be calling Ohlins tomorrow to figure this out.
Yep, spacers in first under the spring. I must have pre-loaded the spring too much with the nut and collar. Your kit came with longer (10 mm) aluminum spacer tubes with black plastic collars on both ends right? The stock units were white plastic I presume,
All I know is something isn't quite right; calling the suspension gods at Ohlins today for some advice.
Welp, the dampening rods must come out and the 10mm spacer removed from the bottom. These spacers are not plug and play...forks have to come off and the dampening rod removed and disassembled. Damn, I thought this was going to be an easy swap. What was happening was their was too much spring pre-load like I said and the springs were rubbing against the inner tube.
Guys with R1M's that 10 mm spacer stops you from using the full stroke of the front fork so if you want full utilization of the full 140mm stroke this spacer has to come out. What a PITA.
I just had my bike at Dave Alexander's place yesterday to get my suspension reworked. Turned out that my fork springs were 1.1s from the factory - strange since the rear spring was a .90. Either way, I left the front springs alone, reworked the rear shock to use a 1.1 spring and an Ohlins ride height adjuster set to +6mm. Then went through and totally reset the static sag/preload settings and did some basic reb/comp settings. Now, I'll hit the track and see how she does, and continue fine-tuning from there.
According to Dave, it looks like there was a switch in the front springs being used between '15 and '16.
The front springs should be 1.05's since that is the heaviest springs Ohlins makes. They may not test to be that accurate but the three lines on top of the springs is what indicates the rate.
Mine still feel pretty soft since I had to crank the preload down to get 30mm of total sag with the stock springs and the Ohlins longer race spacer. I did the same thing by adding a .95 to the rear and left the fronts. Let us know how this works out for ya.
So I had some time to try to get my sag settings in line for my weight (190lbs with gear). The rear shock spring at 95 is perfect; I can dial in maybe 3 turns of pre-load and get 30mm of total sag from fully extended to compressed with rider (me). So I'm set at 30mm, perfect for the street. I can crank it down a few turns and get to 25mm for the track.
The front end is giving me fits; as I suspected these springs are soft. I would like to land in the 30 to 40mm range of total sag with rider and I have to dial in 8 full turns of pre-load to get 40mm of sag. Total pre-load for the M forks are about 12.5 turns in from zero pre-load. That's not good; with the correct springs you should have to crank down the adjuster maybe 1-5 turns max. So this tells me the springs are too soft. When I crank them fully or about 12 turns in my sag goes to about 33mm.
My question to anyone racing a M is what springs are you running in the front? I'm thinking I need to go to the 11N/mm spring maybe in both legs or a combination of 10.5N/mm and one 11N/mm set up.
I seriously can't believe that the stock spring rate of 10.5N/mm are correct. Anyone try the heavier or heaviest front springs?
