Chassis mods for MX

Recommended Posts

While the engine is gone, I'm going to do some work on the chassis.

 

I've decided on a chromoly subframe, tabs removed, and a chromoly tube to replace the gusset that's behind the front bumper. I'm also pondering on doing away with the factory gusset that's under the 2 tubes that run in front of the engine in favor of 2 tubes that form an X. I'd also like to gusset the upper stem mount tubing so I don't have to force the tank off the next time I roll it.

 

Any other suggestions to save weight?

I'm going to try to find a subframe that has the oem style bend to the grab bar that isn't removable so that I can save weight there as well.

 

It'll be powdered for sure.

 

Frame will be white, subframe, nerfs, swingarm, and a-arms will be black. If I can get F43 to build me a bumper in time, it'll be black too.

I agree with r.r.l. above.

 

A bolt on subframe is definitely the better decision.

 

Regarding the steering stem stop, reinforcing is a must do.

 

Also, I believe that you can carefully trim the ends of the steering stop to create tighter turning.

 

This should only be done AFTER you have bolted up your new front end and determined if you need to do this and if you can without creating any issues.

 

If too much is ground off you will create bigger problems.

I agree, just don't take too much off or it could cause your front end to lock up if you turn your bars too far. Just like if it were bent forward.

I want a removable subframe, just not a removable grab bar from the subframe.

 

The stops can't be turned in my case because it the LSR arms that I have. The rims are less than 1/8" from the arms at full lock.

Well considering that I'm pouring my money into the engine build at the moment and that I may have to run different shocks, I couldn't go over $1000 for it at the moment.  That would obviously go up after late Feb., but that's where I'm at now.

LOL. I had an offer of 4x that amount two months ago that I turned down.

$4k?  A Laeger's chassis minus the cost of the pro-trax front end, swingarm, and stem is $4k.  There'd be no way I'd go over $1500.

What exactly is done to that chassis that makes it worth so much?

 

First and foremost, I dropped 11 pounds off the front. The chassis is light. Start looking at and pricing chassis work and you'll see why I declined.

 

They also wanted the a-arms, front shocks, swingarm, etc..

 

They wanted to be able to bolt a motor in and go.

 

I don't need the money so I passed.
