So I've been mulling over the idea of overhauling the forks and shock of my 16 R1 (standard). I have read the dave moss study, watched him setup other r1s in his videos had him setup a previous 15 R1 of mine and been back and forth in emails with him about "unsealing" the KYB cartridge and re-valving everything. I also spoke to some other suspension specialists here in SoCal about drop in cartridges and new shocks etc. Both GP suspension and the guys at Motorcycle service center who deal in K-tech were super friendly and both recommended me some options and got me quotes out same day. With all the said it the options range from $900-$3500 and thats all still rather pricey for me. I'm very seriously considering spending the money but i thought it prudent to get some opinions from people who've done similar work on their bikes and see what the consensus is.

Also maybe some of you just dialed in a perfect setup with the stock parts? Either way just looking to poll the forum.

Thanks

Stock suspension sucks! I bought the Ohlins 30mm cartridge kit and a TTX shock. World of difference. Seriously, it's night and day to the stock setup.

For me, after quite a bit of fiddling, I was able to get a good setting from the front. I never could get the rear settled and ended up swapping in a ya416 shock.

I’m sure you will achieve different results based on your weight and desired results.

I have an m here but can attest that suspension was more worth other power mods in the end

Thank you both for the quick replies.

Just as a reference I'm about 200lbs with all my gear on, mostly a cayon guy but get out to the track and handful of times a year, hopefully more this year. A group rider when i do go, but by no means one of the fast guys

I raced the 2016 season on stock suspension with stiffer springs and got to under 3 seconds off the lap record. The stock suspension damping does have weaknesses in that the high speed compression is generally too harsh while the low speed is more acceptable. This isn't much of an issue if you're not at a bumpy track. The rear shock will run out of rebound adjustment though. I was turned all the way in on rear rebound and would still get rocked out of the seat at certain spots on the track.

I am the same weight as you give or take a couple pounds. I ran 10.0 N/mm fork springs and a 100 N/mm shock spring which is what I recommend you do. This year I ran on the full KTech DDS front and rear and am running 10.5 N/mm fork springs and a 100 N/mm shock spring and may go up a rate in the rear for next season.

I had my 2016's stock shim stack revalved based on Dave Moss's findings (after experimenting w/Jeff Viet's 2015 bike, one of the first ones in NorCal). Stock springs remained since we got the proper spring sag rates. After testing the results on both road and track, for my money I can't really see forking out (haha) big bucks for a set of aftermarket fork cartridges; the revalve really transformed the front end...much more complaint and better feel.

I replaced the stock rear shock with an Ohlins TTX. No regrets at all.

Our team and almost every rider we work with relies on Ohlins fork kits / TTX shocks. There is a definite cost involved, but if the bike is at the track at any kind of pace, it's just incredibly risky modifying subpar OEM equipment over using high-quality replacements. With a well set up Ohlins combo, it's remarkable how much better a motorcycle can feel and allow a rider to perform. Just my .02

I saw what you did there. :lol Note that I would definitely like to upgrade to some carts but it's not in the cards for now. I've done some track days on the modded forks and I'm comfortable with them at my present pace level.

There are plenty of club racers around here who are doing quite well on revalved "sub-par" equipment; FWIW it's the selection of shim sizes for the stacks in the fork legs that's what out of whack. Instead of tapering like a Christmas tree, for some reason Yamaha opted to pretty much maintain a consistent diameter throughout, somewhat like a cylinder. No wonder standard damping rates are off no wonder what you do with the external adjusters.

Needs will definitely be dependent on the rider, but anyone trying to race would be much better served with a proper pressurized fork kit and a TTX GP. The tolerances and quality of OE components are nowhere what those found in a proper set of race cartridges and shock absorber will be. Tires and suspension are 2 things that should always be done right on a race bike. Aside from sheer capability, a confidence-inspiring feeling from the bike is another huge benefit.

That said, if a rider is in B or I group, their requirements will be different from a winning Expert racer.

If you're racing, stick with cart kit and rear shock from Ohlin or ktech, depending on suspension tuner closet to you. Not sure if it's true or not, but Ohlin moved part of their production to China. I knew few racers who went with ktech for that reason. So quality control might be lower. Anyone heard about this?

Otherwise, stock suspension is fine. You might need a different spring and revalving. I have stock suspension on my R1, I was running at the top of A group at COTA on metzeler k3 tires. 4-9 seconds faster laptimes than riders on slicks and and aftermarket suspension. See videos in general subforum.

The limiting factor is the rider, don't buy into you need mods to fully take advantage of a modern liter bike. Spend the money on rider training (CSS or Yamaha champion school).

+100 to this,
wish i had put the $$$ here first before i got all the other little bits that made the bike look cool
it is a different bike with the Ohlins kits
poor performance can only be blamed on the rider now
stock suspension doesn't completely suck in general but, compared to the Ohlins it sux

Lot's to chew on here so thanks you everyone

At this point it's gonna come down to what i can budget. I will probably just run a properly set up stock suspension, until i put put down the money to buy a new shock and fork drop-ins.

Thank you all and please feel free to carry on the debate!

I completely agree with SBK Unlimted, after purchasing a new set of Ohlins RT forks, and a TTX shock from SBK it completely transformed my 2015 R1. The stock suspension is junk IMO. If you are just riding on the highway and slapping back forth to work and back, it will work fine. But once you get to any type of pace on Canyon riding or even at the track, it will fail you miserably.

We were out riding one day with a friend in the canyon's at a really fast pace, he almost wrecked his 2015 R1 cause he overrode his stock suspension, where I had no issues at all.

SBK Unlimted is the best place to buy a new Ohlins suspension setup. Freddy and Alex are great, best customer service and prices around. I've bought multiple sets of Ohlins suspension from them over the years.

I hear you, and do plan on upgrading my fork internals to a set of Ohlins carts next spring (rainy season is just starting here and most of the trackday providers end their year following Thanksgiving).

Fortunately Dan Kyle is right over the hill from me. I got a screaming deal on my TTX earlier this year. :grin2:

Hooli,



I've bought Ohlins suspension from Dan in the past for my 2007 R1, but their Customer wasn't good at all, plus they were very rude and condescending when I asked questions about settings.

I won't ever buy from them at all.

IMO..... Superbike Unlimited provides better pricing and WAY BETTER SUPPORT. They are my go-to shop for doing Business with.

Where is “everyone” getting the fork springs from? Cartridges and shock replacement is wayyyyy too rich for a father of 5. I called Race Tech and they gave me some preprogrammed answer basically summed up by saying “sorry about your luck bro”. I guess I bought the wrong bike. I have always done just springs and oil on my last bikes, using Race Tech springs every time.

I can’t get the front end to stop diving. I guess I could cheat it a bit by going with a 10W fork oil....

I’m 6’8” 220 lbs.

I definitely want at least 1K springs front. Not sure about rear but that’s not nearly as much of an issue about the front.

Summary: where can I buy the springs and what spring rate should I be looking at for the rear?

K-Tech sells springs for use in the stock cartridges and shock. They're about 120 a pair for the front and 120 for the rear. I am about 200 lbs in street clothes myself and when I race with the stock stuff I used 10.0 N/mm fork springs and a 100 N/mm shock spring. After this year on the K-Tech DDS stuff I ended up with 10.5 N/mm fork springs and a 100 N/mm shock spring. I'm likely going to a 105 N/mm shock spring for next year, partly due to lengthening the swingarm a little. At your weight I'd suggest 10.5 N/mm fork springs and a 105 N/mm shock spring for sure. You could get away with 10.0/100N/mm springs but you'll be able to run less preload with the stiffer springs for better compliance when the front or rear is light.

Also, I ran less oil height in the forks for a less progressive spring effect. I think I was at 160 or 180mm on the stock parts. Definitely run the oil lower than stock. Keep in mind the rear shock will run out of rebound damping, it's just a weak point. I had the rebound turned all the way and would still get tossed outta my seat in certain spots of the track due to it.
