The KLX 150 BF (18" + 21" wheels) with a 220cc big bore modification, is a fantastic, legal bike in Thailand. There arn't many legal choices that are light, with a modified exhaust this bike weighs only 112KG.
The Thai guys have discovered this and have boughts loads of them especially with a list price of only 87,000 Bht.
With a 220cc big bore kit, your fuel economy goes down to 24 km/ liter, less if ridden hard off road. The tank is only 5.68 liters, say 1.8 liters is reserve, so you're hitting reserve at around 100km range, when exploring/ scouting into the unknown, that's not ideal. A Honda CRF 250 L, 180km offroad is easily doable by comparison.
A European, quality made, 5-6 liter auxiliary rear fuel tank came up for sale cheap so was worth testing on the KLX 150.
It was fitted to the bike without any modifications to the bike, so can be removed easily.

Custom bracket enabling existing holes in the subframe to be used

With the rear fuel tank lower than the bike tank, a fuel valve is needed to stop the fuel equalizing when full and overflowing the rear tank.

A slight trim on the rear plastic and it all went back together.
Now hopefully 280km range.
