Quote:Tire Size: Stay clear of spoke wheels, but go with cast wheels with those big 16" tires front and rear. They absorb road bumps, will not grab cracks in the road making for a nice straight-line smooth ride even on old roads in need of repair. Stay clear of those skinny 21" wheels as they will make for a horrendous arm-workout. The bike squiggles down the road with those skinny tires constantly tiring you out just like the old dreaded Sportster's used to do. Get the upgraded wide 16" tires as they run cooler and last longer too! It is not unusual to get over 10,000 miles on a set of 16" tires as they run cooler and shed heat to the fat rim like a heat-sink keeping tires at optimum temperature.
http://www.jamesrussellpublishing.biz/sportster1200.htmlThat James Russell dude doesn't seem to like big rims. Perhaps it's just the narrow tires he's complaining about.
One thing that makes me think of wheel size is offroading. Do you really need a 21 inch front for a scrambler? I notice that dirt bikes and dual sports like this. What is the smallest front wheel for off-roading? Has anyone here done a Savage scrambler? Did you use the original rim/tire size?
Now that I look at the above quote, I can't say he knows what he's talking about.
I doubt a Sportster would have 16 inch front AND rear!
