Milling rear sets

Starting tomorrow, I'll have access to a cnc mill to use on my bike for my school project. Going to be making lots of valve casing and other stuff for my build that won't really be applicable to other gs's, but am planning on making some rear sets while I'm at it. What would you all like to see from a rear set if I'm going to be designing some from scratch?

black and silver twin

some thing to move them up and back, dont know how much but enough to get more ground clearance. also try to make the peg have a rough texture so feet dont slip off.  lightness would be a plus but make sure to leave enough metal to be strong. As far as looks, you couldnt physically make them any uglier than stock, form follows function.

If they are low cost enough I would definitely be very interested in a set.

Woodcraft? makes some sweet rearsets, copy that design and I'll pay up to 50% for a set.

Should I bother with eccentric mounts to give a bit more adjustability, or will the array or mounting holes suffice?

Paulcet

I think an array of mounting holes is sufficient.  However, an eccentric mount would be pretty slick, kind of like http://gstwins.com/gsboard/index.php?topic=51846.0

don't seem to be adjustable at

Keeping in mind the GS500 is a budget bike to begin with, make sure your mounting plate will also work with the stock footpeg brackets.

There doesn't look to be a lot of adjustability with the GS as the exhaust on the right side limits the amount you can move the pegs back/down, although up/back there is a little more room.

Consensus from most of the racer guys is that up/back is the desired direction of movement.

The stock pegs are so ugly and cumbersome :( I'll probably ditch them.

I'm going to go to town on the stock pegs with the vernier calipers today to get everything modeled out. Have to head out shortly to do some cncing anyway, might as well try to get some mounts down while I'm at it.


I also have rolls and rolls of carbon fiber sitting there... perhaps cf heel guards are in order.

So, are my new rearsets finished yet?  :icon_lol:

saxman

I have some end mill bits in the mail so I can do the cutting. I'll try to get some renders up shortly.

i've wondered a few times, if guys that loved beautiful shoes waved the same flag as guys that cared what the pegs their boots rode on.... ;)

they're pegs. weld up a couple pieces of iron and stomp your foot on em.

i'm also seen people bend/warp/break those nancy boy aluminum things just by standing up on them. not something i want to happen when the rear wheel is rotating at 700 or so rpm, mere inches from my oh so delicate tootsies.

The whole motorcycle is an exercise in aesthetic design. There are certain areas of the bike that certain got glanced over a little more than others, and the pegs are one of them. For someone like myself that's an engineer and designer, it's a great opportunity to make functional and aesthetic changes in the right direction for very little cost.

If someone broke those "nancy boy aluminum things" by standing on them, that's a result of a poorly design/manufactured part, not an expected characteristic.

eggzackery. i hope your design has some beef compared to the dainty things i've seen out on the road. as far as overlooking the pegs while designing a new bike, well... it's a thing your boot rides on. if it supports the weight, good. engineers would make AWESOME adjustable saddles, with for/aft, side/side, yaw, bladders, and 5 different layers of memory foam + gel + small vibration dampening systems IF THEY WERE ALLOWED. then add adjustable handle bars, adjustable foot pegs (like your plans) and a slew of others. unfortunately the bean counters win, because we americans are cheeeeeeeap.

hope i've leaned you towards stronger vs dainty. thats all :)

now tell them you're making them out of 'billit aircraft aluminum' to really get em lined up and waiting. ;) (joke, not a rib at you)

I've been seeing a lot more adjustability in things lately. Some bikes like the Z1000 had adjustable gauges, the Buell 1125r/cr have adjustable reach on the rear brake lever(possibly the shift lever too, I can't remember), and some other things like that which I can't remember at the moment. I think with time you'll probably end up seeing more things like that. I personally get tired of the never ending HP race with bikes and would like to see some other things focused on, but obviously I'm not the one in charge.
