SR500 simplified brat tracker

Been Around the Block
Not exactly sure what to call it but I'm aiming for a tracker/touring/adventurer look.


here's my rebuild of last winter http://www.dotheton.com/forum/index.php?topic=22428.0
a picture of the first trip I took on it up to the WI oshkosh airventure 250 miles away
as you can tell I'm enjoying my wisconsin cheese a little too much

with school and work I might be a little slow at it but, it has to be done before the weather gets good!
 
Swapped in some 20w-50 oil in the front forks hoping it'd stiffen the front end up enough to where I could lower it Absolutely love the look of it with the front end lowered around 1 inch

went out for a ride and pulled a wheelie, turns out the oil didn't stiffen it up enough LOL

You need to put a spacer in to give the fork springs more preload.Heavier oil won't stop the amount of travel.The heavy oil will only make it react to bumps a bit slower.It won't stop the fender slamming the triple clamps.

The spacer will jack the bike up. What needs to be done is to actually cut down the travel. The fork legs should be disassembled and a spacer put in to limit how far the forks will extent. The spacer should roughly match up to the desired lowering distance. 2" drop will be a 2" spacer. That will also preload the fork springs a bit too. The key point is the fork stanchion tube will be set at the normal position and the travel will bottom at the same point as normal. The fork extension is what is modified... avoiding that nasty dent in the fender.

The damper rod must be pulled out of the stanchion tube and a spacer put in to shorten the amount of the damper rod sticking out the bottom when dropped back in the stanchion tube. If there is a top out spring don't forget to put that back in with the spacer. That is how a flat tracker will shorten the MX type long travel forks and shocks for flat tracking them. Internal spacers to shorten travel and lower the suspension. Nearly a freebie on the SR, just have to buy fork fluid, maybe seals if needed, and some PVC pipe or steel tubing of some sort.

I agree a spacer to increase the preload is a somewhat stop gap measure,but is is better than the wheel or fender hitting the lower triple clamp.The damper rod spring spacer and longer spring spacer is the ideal solution but it can be beyond the tools and abilities of many guys.I think the best solution for a lower SR tracker or cafe front end is a XS250/400 18" front mag.It is some work but not beyond a good machinist.

This should set the bar. If a rider can change the seals in their forks, rebuild a brake caliper or adjust their valves they can take apart a set of SR500 forks and insert the lowering spacer. Forks aren't some magic deal. One just has to be careful. It is easiest to pull the lower leg off by using an air impact to remove the allen bolts in the bottom of the sliders that bolt them on to the damper rod. Then take out the top bolt that holds in the fork springs. Everything can be dealt with from there.
 
Ok... Now that everyones chests have been beaten, and all the roars are silent...

Get anything new dne with the SR Foundation?
 
haha nothing too extreme yet, getting some new tires put on this week. I'm currently attending college and work almost a full time job as well so the little time I do have I usually spend it in the garage. this is my Daily driver bike so it's going to be moving along slowly

But! will be making a spacer theres one yamaha already has in there thats about 3 inches long think I'll be replacing it with a home made one thats around 5 inches long
