the fun bit is putting short pipes on it and then sitting it on your drive and revving the tits off it intermittently for an hour or so while you studiously examine the engine in minute detail then after leaving it to cool for 5 minutes you fire it up with the accompanying backfire and flame spitting and roar off for a 5 minute ride around the block before thundering back onto the drive. repeat until lynched by your neighbors.
alternatively plan a touring holiday and experience the extra excitement of wondering when it's going to break down.
i hear what you're saying about harleys vs sports bikes though but there';s a difference between fun and sheer terror, plus you don't have to wear skin tight leather in bright colours on a harley - somehow i don;t think that'd flatter my figure much.
