Vortex Rearsets and Crashability
Hi everybody. So, looking back at the last couple of rounds with OMRRA, I've noticed something with my pit buddies and wanted to see if others have noticed this as well: Vortex rearsets don't take any damage in crashes - the bike's frame bends instead. I was still running stock with Yosh risers when I crashed, but over 4 crashes by friends with 300s in the last couple of rounds, all 4 have wound up with somebody looking around for a big *** prybar to get it straightened out. Pretty much all of us are a bit concerned about the potential for screwing up the frame permanently.
The footpegs themselves have a scored area about an inch in from the tip that's *supposed* to be designed as a failure point, but none did. And the mounting brackets didn't take one for the team either. I'm considering over the winter just drilling a bunch of Swiss-cheese holes in the pegs to weaken them up a little bit. I'd much rather replace a $30 peg than have my frame buggered up. Any thoughts?

This is a common problem around me as well
The vortex rearsets are designed for supersport frames which are much stronger than our frames. As such our frames fail first. Easiest solution is to run yoshimura adjusters with the stock rearset and swap the peg to the vortex peg. Other solution is to drill through the mounting point all the way and replace the bolts with longer bolts that go all the way through, then secure the other end with locking nuts. As a side effect this creates the best feeling peg setup I've seen on a 300

Yeah, I've seen this too. And it's not just vortex rearsets, it's any rigid rearset.
My advice is to not run rearsets on this bike and only use the Yoshimura spacers with the OEM folding pegs. The guy who bought my 300 racebike took off the Yoshi spacers, laid it down a few times and destroyed the frame. I've seen this with some supersports too. It's not as bad as the 300 situation though.

I put folding footpegs on my Woodcraft rearsets after having to bend frame back after 1st crash. Original solid pegs did break and grind down additional 1/4" off remaining end. But still bent frame mount anyway.
My 2nd crash after that had only minor sliding damage under tip of folding peg. The shifter peg got ground down more than 1/2-way though. Fairing over alternator cover got pinched and ground all the way through along with 10mm of alternator cover. Bent handlebar and ground-down clutch lever. All replaceable parts and best of all, no frame damage!!! Last futzed with by DannoXYZ; October 1st, 2017 at 10:55 AM. |

I should have added, after the crash, my stock bracket cracked, so I now have the Vortices (I can't make myself bastardize that, sorry). I think I'm gonna go with Sirref's idea of using longer mounting bolts, and probably still do some drilling to weaken up the pegs a bit.
Back when I had my SV, I had some stock risers like the Yosh ones, and they bent in a crash, while the clip ons and the frame were usable. I hadn't thought about it, but when I went to order new ones, the guy said that was actually an intended part of the design. Shame that big racing companies like Vortex et al haven't given more thought to incorporating a designated weak point into their parts that'll protect more expensive components.

Really?!? Well this sucks since I have Vortex after breaking the oem when I went down.

It has little to do with it being Vortex. I bent the mounts using stock rearsets with riser plates. The frame is thin there. The best fix is not just to drill holes and run longer bolts, but to drill oversized holes and weld in tubes where the through-bolts go. This will make the frame stronger there.

Tgold is right, the extra step to reinforce the frame will go a long way to minimize the risk of the frame bending there

I think they made rearset mount soft on purpose to prevent the frame bending at the swingarm mounts. That's just a couple inches away and if you get enough force on rearsets, you can bend frame where swingarm mounts. Then it'll be much, much more trouble and $$$ to fix.

Just adding on. Running OEM with Yoshi risers and PSR pegs. I actually love the PSR pegs for the price and for the grip.
I took the Vortex rearsets off my trackbike because of the frame issue. The OEM bracket will break in a lot of crashes, but there are cheap Chinese replicas on eBay now. The only thing I haven't figured out is a cheap replacement for the shift and brake pedals when they get bent way out of spec. |
