As per title, I am newbie motorcyclist without any prior experience in it aiming for B Full.
I have few questions as below:

0) Should I get proper riding boots, glove, pants, jacket and obviously helmet before starting my lesson? if so, how much would that be cost generally for decent kit. Don't mind spend a little bit more on safety kit since i forsee that jatuh bodoh would happen.

1) Is there any biking gear shop that can be recommended where I can go as newbie and try it out instead being pushed around for the sake of sales.

2) Is it necessary to get an personal bike to train on other than going through the bike at Driving School?

3) Is a 150CC sport bike (R15/GSXR150/CBR150/Etc) considered a good bike to begin with? I am considering this over kapchai since sport bike had different riding requirement which I think its transferable to higher CC bike should I choose to do? Or I should be better off with proper big CC bike like Dominar 400 for a start. I tried on those 250 bikes and I find it to heavy for me (skinny arm) hence looking at those 150cc sportbike.

4) I am skinny build guy but 170CM tall person, should i be worried with the heavier bike that was used in driving school (I think Jaguh and Vulcan are used in the place I enrolled in).

5) Is there any advance riding course outside that I can attend once I got my lesen? I have Keith Code book on the side but I dont think it would be helpful prior unless I got the bike myself. I think I am more like "learn as you go" type of rider.

6) This may sound silly but my research suggest to me that bikes price varies between dealership? and availability is depending if one is paying full cash vs someone taking loan (I am more keen on cash payment). Sorry for such Q since I am coming from car world where prices are more or less fixed as per RRP.

Think that what I can think of now.

Look forward for answer from fellow members.

*Seems like now I can get L lesen straight away without doing undang2 test at JPJ, just need find time to convert my lesen.

1) No need to get those protection kits before your lesson... Have a look at YouTube for riding test route / obstacles. You won't be riding that fast in the testing track. It will only be inside the testing track unlike car test / practise, where you will be riding outside the testing track. It will be slow rides, thus you are better with less clothing IMHO.

2) Try to find an academy which will utilise the same track and same bike for practise and also for the test. It will greatly assist.

3) Starting with 150cc may ended you up with quickly to find lacking in power. IMHO better to start with 250cc for minimum power. On a plus side, it is easier to sell.

6) From my experience, it is cheaper to buy directly from an authorised dealer that can be found in the distributor's website. One may need to ask between those authorised dealers to get the best price.

Seems like Z650 is one of the bike that i can grow with it for next few years but D400 at the going used price is also damn tempting too.

There are two school of thoughts where one start with higher cc outright while another thoughts is start small to learn basic then scale up

I dont think I would test the bike for real since i have zero experience with L lesen (Do they even allow L rider to try?)
Worry I will jatuh bodo too
Dont mind go see see look look tho
I have gotten my main gear except pants, maybe I will visit motoworld to have a look over the weekend since they are the one who importing Komine goods but their webpage plenty of item were out of stock 

Seems like they have my size, need to go shop and try since my build is a little bit unique (short body long leg type)
Planning bring my jacket along just to see if both match along?
Got it approx 700 bucks, the liner was fraying a little bit.
The upper part seems to have decent amount of support i think, although I dont want to test it by crushing a heavy bike on top.
Yup, I plan to do cash purchase, but i notice the shop will ask you if you are going buy cash or loan. Some prior reading tells me shop prefer one to take loan cos more profitable.
Also, while browsing certain sales folks try to upsell me (approching 1litre) telling me it is okay for L lesen rider to ride
Currently looking in those over the net to see if there anything I would need to watch out when buying used Z650 or D400.
Seem like other bike in class was MT-07 and in particular which i am keen on SV650 since long running production it is still a barebone bike (no electronic aids or fancy stuff) apart from ABS that seems like a bike that I can grow with

If you dont mind sharing how much do your get for your D400? I checked mudah seems like running around 9K to 10K. Feeling like this would be a good starter bike to go around apart from heavy bike.
