Does anyone out there know or understand how changing the axel size changes the handling profile of the bike? I noticed at Monster Cup a few Ktm's were running different size axels. What would be the cause and effect assuming the steering offset is the same on each bike. Thanks for everyones input on this.....

Im not good enough to tell on a dirt bike, but those changes on a MTB you can tell instantly.

Riders prefer different feels. KTM used to have a 25mm axle up front but swapped to 22mm for production a few years back. The race team however has stuck with 25mm on most of their Supercross and motocross racers. Factory Kawi has 22mm on Bowers and Savatgy, but 20mm on Tomac’s. Width can also play a part in it as well.

The small axle would have a softer feel. It’s not that the small axel is bad, but if you rode them back to back you can feel what you like. On the older cone valve forks they are bigger axel and +2mm longer.

Thank you everyone for your input. Set-up is such a crazy thing and i cant believe how 2mm makes such a difference in every aspect of the bike. Its amazing!
