I have always loved Harley Sporsters, light, lean and quick. I currently have a 100th Anniversary Sporster 1200 Sport. It was offered with a special cam and 2 plug per cylinder heads. It's 446lbs and very quick.
My other Harley is a 100th Anniversary V-Rod 0-85 in 4.5 seconds.
Modern Harleys are assembled with pride, and a pleasure to ride.
One simple word of advice, learn how to stop your bike!
Most new riders start off carefully, then can't resist the urge to punch it.
You can get your bike up to 80 quickly.........stopping it at that speed is difficult unless you are an experienced rider. So learn how to stop before you punch it.
