Re: motorized bicycle for transportation joe last year my hands would go numb from the vibration. i added the springer front end and you would not believe how much vibration it took out of it. i did around 30 miles yesturday messing around after work and vibration was very little unless i went full throttle and even then it was no where near as bad as when i had the solid front end. other thing i noticed was when i go over the railroad crossing i used to have to stand up because it bashed the heck out of me. now it pretty much glides over them. the tension on the spring i have set so with my weight it is just off the mount so maybe a little soft but that makes it glide nicely |
