i don't know what exactly the riding school's position is on this, but i suspect part of the reasons being its simply easier work for them to "teach" B full to those who already has a B2. There are bound to be cases where people could not even understand the operation of clutches in general or who are not comfortable at cycling to apply for B full only to struggle massively. so from the academy's point of view the less hassle, the better it is. this is why i asked about your own competency on two wheels.

the other issues is that the kapcai you learn with for a B2 is really not much different from a granny bicycle (i would argue that even a mountain bike has more aggressive stance) and it doesn't come with a clutch. again i say that it is barely any harder than riding a bicycle, the kapcai is just different from a clutch bike. the 650s they use for B full training have more in common to the bikes than you would be riding compared to the kapcai. since you are riding partly for the fun or it, you probably be looking at bikes that outclass your B2 a year or two  down the line.

parking is really dependent on where you go. some places like 1U and Empire subang are very good to big bikes so you don't have to worry that much. most people who use big bikes to commute either commute between home and office where  they know the safety of parking, or in malls that have good big bike parking or rarely park it out of sight. if you are talking about a go anywhere bike for general commuting in the city, then i will, as usual, suggest getting a scooter that thieves generally do not target.

I also taking my BFull at imkeda. Sitting here waiting to sign out from second practice. Haha

ya, open already. suppose do my practice this afternoon also but rain, i stuck in office.
The one i using is a black ER6, there is another red one i din see before.
