Sportsters are made to need upgrades. like most Harleys, just more so. They need seat and suspension badly and a bigger tank for most.
After you do that they make a nice bike. You can buy an 883 cheap used low miles, bore to 1200 and have a fun bike, with the shorter gearing, small port heads it has huge torque. Still 883 insurance rate.
The touring models are much better out of the box. They still like fork and shock upgrades, but it is not critical.
Many of the factory demos have a free 4 hour ride program. Be early, they sell out fast.
