cotter pin size

cotter pins for securing your pedal arms. sold individually. different mopeds use different size cotter pins so check before you buy.

to get these in properly, consider getting a cotter pin press tool!!! it makes a huuuge difference especially if you have lots of bikes or are wrenching a bunch. it will get in and out some of the toughest cotter pins without damaging them and keep em in tight!!!

attn!! news flash!! please keep in mind that the pedal shaft cutaway WILL affect the size of cotter pin that works perfectly with your pedal arms = infinite sizing possibilities.

puch and SOME tomos use 9.5mm pins.

we carry sizes - 8mm, 8.5mm, 8.8mm, 9mm, 9.3mm and 9.5mm - check the drop down menu for available sizes

the 9mm size now features awesome m7 threading for crankin down harder n removal with the aggressive hammer lifestyle we live

Honda camino hobbit Pa50 use 9.5mm cotter pins if you are using the stock pedals/pedal shaft.

sold BY THE PIECE in case that isn't clear from the photo of one cotter pin and the second sentence above. hmm.

NOTE!!! if the size/color/make that you want is not showing up in the drop down menu above, that means it's out of stock for now. you'll have to find an alternate size/color/make or wait til the one ya want is back in stock! sry!

9.3mm is tomos oem # 229227
9.5mm is tomos oem # 206714
tomos oem #217348 is also a cotter for A3 models, but we don't know the size yet!

4 of 5 Works as advertised July 7, 2020
taco eater : Chinatown Kicks from Boston MA  
I sent away to France for a set of these before I thought to check Treats, can you believe it?  It turns out the ones from California fit just as well. 9.5mm for a Maxi, just like it says.

5 of 5 Pedals pedal now. February 5, 2020
taco eater : Scott Dawson from Van Nuys, CA United States  
Used 8.8mm on Vespa grande, pedals no longer flopping around uselessly. Don't over tighten nut, you'll break it!

4 of 5 meh.... it holds my pedal arms on. March 9, 2019
taco eater : Mason Shreve from Carrollton, OH United States  
I have gotten a few of these now for various Vespas, maybe I am ordering the wrong ones. They are the same diameter as my old ones 8.8mm , but the ramp is always to aggressive. I can't even get the nut to start, it is nothing a grinder can't handle, leaning out the ramp, it just would be nice to not have to.

The 8.8mm and the pedal arm extender worked perfectly on my Garelli Rally Sport. Now I can clear my exhaust and all the gaps at the skate park!

4 of 5 Fit after filing. April 10, 2018
taco eater : Anonymous Person from MA United States  
Dunno exactly what size I needed. Old cotter pin had a 9mm diameter but the cut on the crank kept the cotter pin from going deep enough. Threads didn't stick out the other end. Fortunately the cotter pin is fairly soft metal so a few licks with the file, test, file, test, ect. until it fit and it works fine! I think.
