Large displacement sport bikes are generally referred to as superbikes or in similar category in malaysia. No thanks to that, our government impose high taxes on them. making a proper bike with decent power and brakes expensive to own and maintain, yes imported parts are taxed too.

sports bike like er6n are popular due to local assembly. much like cars, lower taxes. yet it cost in the upper 30k region. a slightly different variant, the versys is in the 40k region. top speed in the range of 180km/h if i'm right.

superbikes usually have displacement close to 1000cc, then like supercars. they have their sports category and touring and classic.

Riding one requires skill and experience. Big engine comes with heavy weight and extreme power. ex5 is more like a bicycle to people who rides superbikes
steering is partially done with shifting body weight. takes off like a jet plane on the runway and stops as if you dropped a ship's anchor down the road.

Once you've rode one, you'll understand why people love riding their machines on twisty roads.
