On a smaller M/C it creates more line pressure with the same finger pull. The travel when the bike is stopped may be more but under motion it's not much different than stock. The increase in line pressure makes the brakes work so much better you don't have to pull the lever as far to get comparable braking.
I went with dual disc, steel lines and the stock 14 mm M/C. The line pressure didn't change much but the pressure squeezed twice as much brake pad onto rotors. I think this will be close to one disc and the 11 mm master.
I haven't tried that set up yet, I guess I should get one of those XT225/TW200 M/C's and try it.
I have thought about it before but didn't find an M/C that used an adjustable lever. If that TW200/XT225 M/C can use the stock XS650 lever I'll like that.
