The only 2b bikes I know that looks big is the Aprilla 125 and
the Varadero 125.
But are u thinking of riding a Class 2A or Class 2 bike in the
future as soon as ur 2B probation is up.
If yes, then get a 2nd hand Ah peh bikes: Honda CG125, Yamaha
RXS/RXK/RXZ (eariler models), Suzuki GN125 or eariler Honda Phantom
150, etc. Cheaper, Then invest on ur dream 2A/2 bike.
