Patong Hill isn't Bangkok's flat streets — It's steep limestone switchbacks that'll destroy you on those tourist 125cc bikes. The gradient from Kathu to Patong viewpoint will have you white-knuckling at 20kph.

Get at least 150cc for serious island exploring. Local shops near Chalong Circle rent Honda PCX around 400-500 baht daily — Way more torque than those gutless tourist 125s for 250 baht. You'll actually maintain speed on climbs.

The Kata-Karon coastal road gets genuinely dangerous when wet during monsoon season. Seen too many tourists with serious road rash from losing control on those curves. If you're not confident with hills, just use Bolt (80-120 baht short trips) or the blue songthaews.

Never attempt the back road to Big Buddha on a 125cc during rain — It's unpaved limestone that becomes a slippery death trap.
