12. BF Injection
Beach Buggies are cool. Therefore the BF Injection is cool. I dare you to argue with that unshakable logic. Ok, they're not very fast. Plus they can be quite wide depending on which version you are driving. However they have great cornering, they're very durable and it is near impossible to flip a BF Injection onto its roof and have it stay there. Plus we know that we'll be touring the majestic peaks of Mount Chiliad in GTA 5. Give the Injection 4 wheel drive and you have a tough off-road vehicle.
13. PCJ-600
The PCJ-600 along with others were the first motorbikes that were introduced to Grand Theft Auto. Chances are it was the fist motorbike you rode in Vice City. The scooter doesn't count. As the vanguard of fast things with only two wheels I'd be very surprised if this didn't make the cut. It will though, as it looks like we'll be getting a bigger playground than Liberty City offered us.
