Nobody knows for sure, Xena 2 with alarm used to be highly recommended.
To me, a decent chain with padlock, locking up both the wheels to the fork and swingarm is the best.

Just bear in mind, a lock can only be deterrent to a thief. Use some common sense how to apply the lock.

Here are some of the things they could do to mess with your bike:
- Rim and fork lock - Low. Too many weak link, so IMO it is not secure.
- Disc lock - Moderate. Thief can remove your rim, open the disc, and put back the rim and ride off. Cheap locks are not stainless mechanism, so after a while, the key mechanism will jam inside and cannot be opened.
- Standard steering lock with magnet cover - Moderate. Can be dismantled, or break open by force. In some cases, the steering head will loosen first before the lock is broken. So, in case your bike kena langgar, check the steering lock for cracks and have it replaced.
- Rear sprocket padlock or disc lock - More secure than putting the disc lock at front disc, but can be messy due to chain oil.
- Long chain with padlock securing the bike to a pillar or something - Must have good padlock. More secure, but troublesome and can scratch coverset.
- Bicycle lock - Cheap one can open with hammer.
- Immobilizer - some add on electronics to guard your bike from unwanted ignition. Can simply DIY and hidden switch to the battery terminal or the CDI. Make sure wiring is installed correctly. No alarm is better, otherwise the thief will know your bike got alarm, and prepare for it.

For a good padlock, prepare to spend RM50+ each.
If the padlock is RM50 for 2 or 3, it is for hiasan, and will not stand a chance.

Cheapo trick to increase the octane number (RON) of the fuel. Sorry not much time to elaborate on this, but you could google about naphthalene (substance that made up those 'ubat gegat' or mothballs), their effect on fuel's octane number and what RON number did with fuel consumption.

depend on what grade material u want to use..
starting from RM250  to 1500

You'll need to pay for some extra stuff, like footrest modification and labor charges.
I'm guessing a ballpark of RM300~500.

Parts you'll need: Rim, disc, brake pump, brake hose, reservoir, brake fluid, brake pads.
Mods you'll need: Swing arm for caliper mount, footrest for brake pump, brake reservoir mount.

Not normal. Usually if battery is weak, bulbs will start to burn especially headlamp and brakes.
Use a voltmeter to test the battery terminal, when engine not running, idling and running RPM. See what are the voltages. They should be around 12.4 and 13.6 volts, not exceeding 14.4V.
