$100 919 Shock upgrade

I live close to a tuner guy that has done some pretty impressive work for me in the past. Just for fun I dropped off my shock and he rebuilt it

He changed the oil, moved some shims around and I'd say it's one hell of an improvement. I'll know more tomorrow (placebo effect) but so far I'm not preparing for the dreaded sharp edged bumps like I used to. Floats over them pretty good and doesn't seem to wallow as much.

Funny thing is, he's nearly positive the Race Tech Gold Valve will fit in there. I didn't want to gamble but he said there's no reason he can't see it fitting.

Definitely update us. I live up in FoCo so if it works out well I will look at talking to the guy in the fall when I am not riding as much.

Going to a supermoto track tomorrow to find out for sure, but my initial thoughts are that this is a very worthy mod for those that don't want to spend 1/3 of their bike's worth on the rear suspension.

Please forgive the Ohlinsophiles: they are desperately trying to convince everyone else that their solution is the only one worth doing. Granted, Ohlins are fine shocks, but they aren't the only ones, and indeed not the only avenue worth pursuing, especially for the monetarily challenged.

Case in point: a while back I got a shock for a 2003 Yamaha R6 from a seller on ebay for (believe it or not) $20 including shipping that is almost the right length, can mount the 919 spring, and can be made to fit. All that needs doing is to tear it down, replace the seals, and adjust the shim stacks for the different loading according to calculations comparing the R6 secant / cosecant linkage to the 919's non linkage sine setup. Piece of cake. Not bad for $20! Even if I took it to Sage Suspension it's still only $120. Much better than $800+ and I gain considerable knowledge in the process! Besides, I want to discuss an electrorheological shock with Steve.

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

Now that's a discussion during which I'd like to be a fly on the wall. To the best of my knowledge, that's not technology that has made it onto a motorcycle, yet. It seems like it could prove worthwhile to develop, though. The application in cars lends itself most to cars with a sport/grand touring style of driving due to the inherent flexibility of such a suspension. That would be perfect for a bike like the 919.

For me and many others the Ohlins is off the table. If you stay with the 9'ers shock at least the spring rate is fine (for most) and you don't have to worry about length. That right there is enough for me to continue working with the stocker. It is NOT that bad of a unit, what do you think comes on something like a Ninja 300? Racers re-build those shocks all the time.

This guy Steve Sage, I'm telling you knows his stuff if he says a Gold Valve will fit, I for one believe him.

Headed out to the track today

So I'm not going to pretend I know any more than the average guy when it comes to this stuff. I've owned a ton of bikes and modified the suspension on more than half of them and I'm still learning.

That being said this seems to be a very cost-effective and worth-while modification. I have not tired it with stock forks because I had my F4i forks with the Ohlins cartridges mounted but the rear end seemed to stay completely composed and less harsh over sharp edge bumps. The street ride I took last night seems to have confirmed that Steve was able to change the shim stack and match it to the oil weight very well.

When you consider the next best option is to buy and F3 (or I guess R6 now) shock, change the spring, mess with the length and possibly the internals, this mod it to me one of the best bang for the bucks I come across for the 919.

Please keep in mind I am not an expert. I seem to be in the minority in believing the stock shock is not best thrown in the trash. But damned if my bike isn't railing corners better than it ever has before.

I paid Steve $105 ($100 sounded better in the thread title, sorry) I am not affiliated to him in any way whatsoever, so contact him about pricing first.

Thanks for the update, very informative. I love my 919, but just don't see spending a fortune on suspension, by the time I spent the $ to upgrade it all I could have bought a clean low mileage Triumph triple. (Been looking). I'll check out Sage and maybe put the triple idea aside for another couple years.

Thanks for the quality write up Ditch! I'll be suggesting this route for my brother and father's 919's. Just curious about the R6 bit you mentioned. People are mounting R6 shocks? This is the first I've heard of it.

Exactly my reasoning for going with a rebuilt F3 shock!!!!!

Just a bump for those who are also curious.

I am modding my brother's 919 while he is deployed as a welcome home present. Painting swingarm, 520 conversion, forks, headlight, bondo/ painting the tank. Also will be doing this mod, so thanks ditch!

After a couple of months, Id say this is not worth more than $100 but still money well spent.

Becuase a polished turn is still going to stink. But it's a lot better option for some than spending 1/3rd of the bikes value on an Ohlins.

Hard to say but that would mean spending more money and $100 is the max I'd want to put into it. A different spring and you might be 1/2 way to a Hagon money-wise

Looks like I will have to do just this for my girls 599.
