Hmmmm.I've got three bikes.Had them all for 40,30,29 years!A couple of others,smaller commuters,but moved them on just before they wore out.Of the ones I kept a "low rider",a parred down cafe racer and a bulk standard sports tourer.Of the first two I love the look that I have imposed on them.The two modified bikes are"improvements", in my opinion,on the originals.Streched or regressed versions of the original design intent.They "needed developing".
The low rider is a cruiser(tractor) and I did many miles touring and commuting.No serious need to get to the next stop in a hurry!(work especially).It is unique,comfortable and needs an engine overhaul every 25,000 miles...I since sold the spare swapping over motor.
The cafesque looks mean and is very stimulating,no fairing,loud and attracts attention.It is unique as well but it is very demanding and you get there early but bent double and shagged out.
The sport tourer(brick)is the one I rely on when I want to get there in good shape.It is utilitarian,reliable beyond belief,goes unnoticed,won't be stolen and is my go to ride when I'm in any doubt.This bike I could not improve to give me a unique niche.It just does it so well.
My analogy is:First love,Sexy Bitch and Wife.....
Modifying,out of genre, a good original brick would be like drawing a moustache on the Mona Lisa.I think best draw it on a Picasso or perhaps a Salvador Dali where it might add some extra amusement ... :euro Leonado would not be but the other two would.
