    My buddy just finished a custom bagger. Around 2010 ultra CVO. He put 26” wheel up frt lowered with air ride and stretched the bags about 9 inches further out the back. He was driving around 105mph crossing a high bridge over a river with a crosswind. The bike began to fishtail. Fortunately he recovered. My question is could all the modifications cause an updraft to make that happen? He had the rear axel checked about less that 1/4 inch out( that may be from fishtailing). Any theories? Thnx in advance!

    Don’t know what caused it but theres a reason engineers get paid big bucks to design stock motorcycles. The magic word is stock.

    I agree, when you make those mods you change the geometry.

    bad tire, oil spot or other various debris, suspension parts gave up the ghost... could be any number of things.

    but going 100+ mph on a big wheel is just stupid.... and i love big wheels as show and cruising bikes.

    Driving over a high bridge with crosswinds going 105 with a big front tire? Hmmmm. Lot of things could happen.

    Not my style either. I just think drastic changes in design can be potential problems.

    I agree Bobby,.......While there is nothing wrong with modifying a bike, I would stop short of body and chassis changes,.....like you say, someone is getting big bucks to make it safe,......
