Default Fender clearance front and rear 2003 Softtail Heritage

Hello all,

Always have wanted a Softtail bobber and it looks like this is the year. Starting out with 150/80b16 tires front and rear. Anybody have a scientific value on how much space is needed between front fender and tire sitting cold? Then, same question in the rear with some tire growth at speed along with who knows how much suspension bounce as it will be mounted to the same frame rails the typical fender is attached to.

Any guidance is much appreciated.

A radial tire grows maybe 1/8" in radius at high speed, and nothing in width. So for your front fender you can go very close.

For the rear you need to take into account the suspension bottoming out, if you are running with a passenger or heavy luggage.

Thanks for the info on the front. Any idea how much give is in the rear suspension at full crunch? I am afraid of cranking in the fender frame mount to pull it down and don't really want to guess.

My 04 has SE rear shorter spring/shocks. About a 1" loss of travel in suspension.

I set shocks at the minimum pre-load. Doesn't take much to hit the bump stop with my 190 lbs.

Not going to hurt it pulling it down with straps.

You need to know what you have if you start filling that wheelwell up. There is bolts sticking in it and a rear taillight harness.

Got it!

I will rachetstrap the back end down to see where it stops. I am removing a good portion of the rear fender, but the bolts that mount it will still stick out on the inside. Thanks for reminding me ot that!
