Cheap damper on my 150f


Recommended Posts

I mounted up a OEM gsxr damper to my 150f to see how it is.. I only got a chance to ride it around a field outside my neighborhood, have yet to trail ride it.

I already put thicker oil on it, but might have to go even thicker. I need to go spend a whole day on it and see how it is, I don't want TOO thick of fluid and have it strain me to ride.

I got the damper for free (although you can get them on ebay for $25-$35), the steel for the brackets I had laying around, and spend about $10 on bolts and ATF fluid for the damper ๐Ÿ˜

I haven't had enough time on it, I only rode like 10 minutes in a open field trying to hit any bumps/off camber spots at high speed I could haha

I wanna go as thick with the fluid in it as I can without making riding HARDER

my main goal is to soften the blows when I hit a log or something and my handlebars go slamming to one side then back in a straight line, hopefully get rid of some fatigue. I can definitely feel a good deal of resistance if I try to go from lock to lock with the steering when I'm stopped, but when I'm riding, I'm hardly turning so it's hard to judge if I need more damping or less ๐Ÿ˜

I'm hoping to get it dialed in where it helps fatigue instead of adding fatigue to say make it more stable. But gonna be hard since I can't adjust it on the fly for slow speed trail riding, and fast riding

Also I got the used Renthals and Acerbis hand guards off my friend for $30 that I added yesterday too, the bars look new, the guards are scuffed bad but still solid as can be, I've been wanting Acerbis bark busters for a long time now ๐Ÿ˜๐Ÿ‘

Post back and update the tread. Should be interesting how it works out. I've always thought those things were for high speed stability . If your bike susp is set up to turn shaper[more weight on the front] your bike is more prone to headshake at high speeds. The damper should minimize this to some extent.

Im not an expert with these so someone else might chime in . GOOD idea though. It's amazing the stuff people come up with on here.......lol.

So yesterday I finally got out to ride for a good long day, and WOW what a difference the damper makes!

I was clearing trails at my friends new land, tons of logs down everywhere, lots of tall grass so I can't see the logs...

I rode over half the day with the damper, it was kind of hard to tell if it was really helping or not. Halfway through the day one of the nuts used to mount the damper fell off..

I went back to my truck and completely removed the damper since I didn't have a extra nut, then went back out to ride. As soon as I left my truck I went full speed balls to the walls through the trails, instantly I noticed the steering was way more touchy, the bars tended to slap back and forth a lot more as I hit logs and off camber parts of the trails. I rode about 5 minutes after removing the damper and I had arm pump BAD! real bad.. I had put in over a solid hour of run time on my motor before the damper fell off, and 5 minutes after losing it I went from not getting tired to my arms being completely exhausted..

The damper stopped a lot of arm pump I get riding as fast as I can on rough trails, once the damper fell off it reminded me of how every other time I rode my bike has been, I get arm pump in 5-15 minutes then I need to either rest or struggle through it and slow down.. I'm definitely putting the damper back on, still need to experiment with how thick of fluid goes in it. Right now I'm running mostly ATF fluid with like 10% 80w90 gear oil. I might try to go to like a 20-25% mix of gear oil and see how that feels. I just don't wanna go too thick on the oil and make it harder to ride, the main goal of this is to make riding easier, and stop some fatigue from me having to fight to keep the bars from slamming back and forth. :banana:

can you post pictures of the brackets you made, and how you attached it to the frame? This is a genius idea

I wish I could take all the credit๐Ÿคฃ I picked it up from sport bike stunt riding, lots of people make brackets something like mine to mount gsxr dampers to their sport bikes for doing stoppies.. Basically if you have 'mediocre' fabricating skills, basic tools, and around $30-$60 for materials, you can have a cheap damper :banana:

I wasn't sure how it would work on a dirt bike, so far I'm loving it. I originally fitted the damper, made my brackets, and had it looking great, but the damper sat too far forward so the steering was limited by the damper, which would end up damaging it... So I had to tweak the brackets around, and get them to hug the forks and frame closer, now I can go lock to lock and the damper still has a tiny bit of play left :eek:๐Ÿ‘

The brake line just barely clears with the stock "O" holder bent.. But I'm going to flip the stock holder around, and move the line to the back side of the forks so I can get 100% clearance... I'll make sure not to give the line ANY chance to get caught in the wheel ๐Ÿ˜‰

(image shack has been sucking lately so I'm just going to link the pics)

The two holes on the bracket on the frame are cause the one further towards the gas tank was too far in, so I just re drilled another and the damper fit perfect

The only thing I'd change about the design would be to use both the tabs on the frame for mounts instead of just one.
