I've grown more bored with riding on the street than the bike itself. Primary reason for this is, there is nobody left to ride with. All last summer and several thousand miles, I rode by myself. Used to be some sportbike people that I rode with, but all of them were young, and got married or otherwise went broke and sold their bikes. The local sport bike message forum finally gave up and shut down because everyone was talking about guns instead of bikes, so there is no real way to locate anyone else. I seldom even see a sport bike out in the back woods twisties anymore, only cruisers. The few Busas around here all have long swingarms and the riders don't like to leave the city limits of Springfield. Pretty much the theme of all the sport bike people here at the moment, extended, lowered, ride in city traffic, and complain about the police and people trying to run over them.
Track days are good, but the closest track is over 200 miles away, and figuring track fee and travel expense, it costs me a minimum of $200 for 6 or 7, 20 minute sessions. Plus the track folks I find to be mostly aloof and stand offish from everyone except the little group they're with. I may do a couple next summer, but it's hard anymore to justify from a "bang for the buck" standpoint.
That's why I've pretty much parked the Busa and went dirt riding. Always someone to ride with, all skill levels, open bunch of people, excellent riding areas, and great fun. Racing abounds, from woods to track, there's one at least every other weekend, most are within 75 miles of my house, and total cost is 1/3 of a single track day. Then there's motocross. $15-$20 and a 10 to 40 mile drive will get me a full day with unlimited track time (no 20 minute sessions). And I'm finding real quick that it has everything a road course track day does when it comes to skill required and adrenaline rush to be had (air out a 70' double and tell me your heart isn't in your throat). Plus the people are always open and friendly.
I don't plan on selling my Hayabusa, because I still like to go ride once in a while, and hopefully someday I can hook up with some other people who like to actually ride. But for the most part now, I'm on knobbies.
