The Monty Cranks I use are longer than the OEM Luna crank arms that come with their pedal kit. Monty does make crank arms the same length as the Luna set too.

Due to a little mishap my left pedal crank was bent enough to cause it to foul on the kickstand. I was able to bend it back using a vice and hammer. It motivated me to purchase an alternate set of cranks branded by “Jitsie” sold by the same retailer I used to purchase my Monty cranks. A fellow member on a private Sur Ron group had “successfully” installed a set of Jitsie’s on his bike so I thought they would fit on mine. Not so unfortunately. Either my kickstand or my pedal kit tolerances are different than his. Another user found the same issue with his kickstand and the Jitsie’s. He had to bend his stand inward toward the swingarm until it cleared. I prefer to not do that as a crash on the left side could then cause the stand to foul the swingarm.

The length of the Monty cranks.
Monty cranks easily clear the kickstand. Loads of clearance with the Monty crank.
The Jitsie cranks although less prone to bending do NOT clear my kickstand so I did not use them. The Jitsie crank fouls on my kickstand.

I would prefer the Jitsie’s because they do not have the same bend and material cut away as the Monty’s so I surmise they will not bend as easily under high forces. Keeping the pedal cranks level when bouncing or jumping won’t bend them. But having one pedal lower and then bouncing or landing on the down pedal produces enough force to bend the crank depending on rider weight. Just be aware that the Jitsie brand may not fit your pedal kit. It didn’t work for mine.

Here you can see the material that is removed from the Monty brand. I’m sure it’s to save weight, but I’d rather trade that for strength on the Sur Ron.
The Jitse’s are slightly shorter than the Monty brand.
The bend of the Monty crank is evident.
