The CBR300R runs Honda’s 286cc single-cylinder engine, liquid-cooled, with a six-speed manual gearbox and around 30 horsepower on tap. Curb weight sits close to 163kg. It’s the same 300-series platform Honda has sold across Southeast Asia for years, so parts and servicing are easy to find anywhere in Thailand, not just Bangkok.
Compared to the GPX GR200R already in the fleet, this is a genuine step up rather than a side-grade. The GR200R is a 200cc manual with sport styling, this is real 300cc displacement with more midrange pull and Honda’s six-speed box under it. Riders coming off a 125cc automatic will feel the difference in the first few blocks, and anyone who’s ridden a manual before will notice how much more relaxed the highway gearing feels.
Honda’s name carries real weight with visiting riders. It’s one of the most recognized sport bike brands in the world, which is not something RentLab’s other 300cc-class machines (GPX-badged) can claim to the same degree. That recognition matters more here than usual, since this is the one bike in the fleet built for longer rides outside the city rather than pure Bangkok commuting.
The CBR300R rents for 690฿ a day on the 2-6 day rate, a step above the automatics in the fleet and in line with what a real manual sport bike commands in Bangkok. BSR Bike Shop’s Honda CB300R, the closest direct comparison in the city, runs 900฿ a day in high season. RentLab’s zero deposit still keeps the total cost lower over any real booking length.
Unlike the rest of the RentLab fleet, which stays inside Bangkok, the CBR300R can go up to 150km outside the city on top of full use within it. GPS monitored, same as every RentLab rental.
