Justkir, there are loads of magazines, but the best ones I enjoy looking at (not read cuz I can't read Thai) are:
Race Bike
Bike beauty
BMO
Unfortunately, you will only find the mis match no color co-ordinated modifications of the Thais which I am sorry to say, are F#*KED up compared to mods in other countries which look much better and road worthy.
Not much Spark action in the magazines here because the Spark isn't praised that much as a Yamaha Mio or a Honda Click and all those other stupid bikes.
Alot of people here be telling me the reason why Thais don't like the Spark 135 is because the engine does not last long compared to a Honda Wave aka Supra or a Honda Sonic.
They can only tell me that but no exact specifications because Thais aren't very good, actually are horrible when it comes to detailed descriptions and specs.
I believe they think this way because the Spark 135 requires professional attention and dedication to maintenance, unlike other standard bikes. Thais are lazy when it comes to maintenance so that is why the Spark is pushed into the darkness to give way to Mios and Clicks and Supras etc.
Although, Thailand out of all other Asean countries, carries most of the aftermarket and upgradable factory parts for the Spark 135, which is good for me and bad as well cuz I don't have much money to throw around
