I have now the biltwell murdock risers(1" clamp) and already got the shims for to clamp to take a 7/8" bar. I really want a known motocross brand bar like renthal or protaper, because they are proven to be strong and rigid. The problem is that I dont want the crossbar brace, and therefor I need to go up to 1-1/8" bar(only at the clamp, and then goes to 7/8" on the ends) to have a strong bar.

Because im cheap and dont want to spend my money on the 1-1/8" hardcase performance risers, I want to customize either the bar or the riser.

Should I just get a 7/8 bar and remove the crossbar brace or get a 1-1/8" bar and do some work to make the 1" clamp bigger? Any idea on how to do it in a accurate way?

Thanks!

 

If your goal is to end up with a bar that's "proven to be strong and rigid" and is designed with a crossbar, I think cutting out the crossbar would directly work against your goal...

 

Yeah I know

 

I have a hard time imagining a 7/8" bar being stiffer than a 1" bar with equal tube wall thickness.

Is this for stunting?
You already have solid bushings?

Seems like there are quite a few bar makers using .120 DOM steel tube...

 

Yeah, already have solid bushings. Not 100% for stunting, wheelies now and then, but not hardcore stuff. Main reason is to use 7/8 parts like brake and clutch(that I already have) and smaller grips to have a more mx feel. Been riding the 1" grips for a while now and I dont have any problems with them, I just prefer 7/8" grips.

A lot of the new motocross bars have a 1-1/8" thickness where the clamp sits, and then tapered to 7/8" on the ends. I dont know which one are the stiffest, 1-1/8" - 7/8" or 1", but for sure stiff enough.

I just came across a German brand, LSL, that have 7/8" bars with 4 mm thick aluminium and they claim it is way over the TÜV standard, 60% better. Maybe I will try this brand. They also say it is safe to make holes for internal wiring.

 

Gotcha.

Sounds like risers are your best option, then. Without a jig and mill, I don't think modifying a 1" set is a good idea. Just my opinion. A machine shop would be happy to give you quote, though.

 

I have access to a mill and jig, but how do I mill out a perfectly 1-1/8" throughout the clamp... Yeah I should ask a shop for a quote
