Well im starting to get itchy, and am searching for a track bike. Im having issues making my mind up on which way i should go. Im looking at a few bikes. Honda cbr250rr Aprilia rs250 Yamaha r6/generic 600cc ss bike yamaha r1/generic litre bike Ducati 749 honda 900 fireblade This bike, im basically going to treat as a write off. So... Honda cbr250rr - Im looking at this bike, basically, due to the fact, you can pick up something for around 5 grand, and thrash the pants off it, and sell it two years later, thanks to the learner market, and not lose much on it. Id imagine this is a very reliable and cheap to run bike, and might even serve as a commuter. My main issue with this bike would be can i get replacement plastics etc(cost?) and whats the cost of a complete rebuild? If anyone has any significant experience, can they let me know how the brakes, suspension and general trackability(new word?) of this bike. Aprilia rs250 - I kinda just looked at this because its in the same ball park cost wise as a cbr250rr. Well, its the bridge between the the cbr and the r6...I kinda like it for the same reason i hate it...i view it as, no matter how rooted this bike is...its only ever a rebuild away from new(engine wise). I hate the bike, because the way i intend to ride it, im looking at 5000km rebuilds. Ive heard there are issues with parts? This bike gives me a bit of wood though, the thought of drilling bigger bikes in the corners gives me a bit more wood than blasting the r1 esque bikes down the straight. r6/generic japanese middleweight - Enough said...would prefer a fuel injected model, which unfortunately puts me up there in price, unfortunately, its hard to justify popping 10 grand on a middleweight bike, when you can get an r1, for roughly the same price. Unfortunately, these bikes, seem to be the popular class at track days. Unfortunately, i have trouble justifying there expense, when realistically, the bigger litre bikes arnt that much more expensive. r1/generic japanese litre bike - Seems to be something im leaning towards, im prepared to throw out the fuel injection and just go for a carbed 98-2000 model, for under 10k, the larger engine seems to inspire a bit more when buying second hand. Ducati 749 - There are two other dukes in the garage at the moment, and id love to race one, unfortunately the initial cost, is whats drawing me off, for my intended use, there not really that bad service wise, and i can rest assured the engine has basically been built to be thrashed. I also value the superior suspension and braking that this bike has. Unfortunately i love ducati's and could find myself babying it. Honda 900 - There about 5-6 grand now...and i wouldnt mind dropping it. There quick in a straight line. My issue is corner speed. I spose in the end of it, im not against having a smaller capacity bike on a track day. Just looking for some opinions on which way to go.
