When making my desicion to buy I looked at the following bikes:
SV1000, Z1000, TL1000, SuperHawk, Honda 919. All of these bikes have there strong points, but I chose the B12.
The simple fact, you really get allot of bike for your money, especially when buying used. I bought an extremely clean 02 with 4,000 miles for $4000. I was drawn to the big bore, bullet proof motor, easy maintanence, and abundant aftermarket parts. I have a naked B12, but in 15 minutes I can throw my windshield and luggage on, and have a very capable sport tourer.
IMO I think a stock B12 is very bland, and lacking personality, (no offensive to anybody riding a stocker) but that is easily fixed with aftermarket parts. There are many parts available to allow you to "customize" the bike to your liking and provide it with a bit of individuality.
This however is just my taste, and everybody's is different.
The Bandit is one of the few bikes I have seen that can be so many differnt things. Everybody buys a bike for differrent reasons, but I have seen Bandits that are set up to be boulevard burners, stunting bikes, sport tourers, or kept stock as just a great do all bike.
My previous bike was a Yammie R6 (which I loved) so I not expecting much in the handling department fro the B12. The B12 was to my surprise not too bad. The brakes are a little lacking, but swapping to SS lines and different pads fixes most of that.
Everyone who has ever ridden my B12 comes back with a big smile on their face. So if you are looking for a "cheap" big bore bike, with loads of available aftermarket goodies, and a motor that will run forever, the Bandit is the way to go.
I am very pleased with my purchase and have absolutely no regrets. Of course if I had the money and space I would own one all the bikes listed above :)
