Today let’s talk about one of the best motorcycles ever made, the Honda CBR250RR MC22 also known as CBR Gullarm.
Let’s talk a bit about the history of this bike. Honda CBR250RR MC22 is based on MC14, MC17 and MC19 and was first released in 1990 with a new improved look and technology. Brom 1990 to 1999 there were 3 models of this bike with power output between 40 and 45BHP.
This bike was mainly designed for the JDM market, also known as the “Japanese Domestic Market” this bike was never directly imported by Honda to anywhere else, but 3rd party resellers imported this bike all around the world. If we mention more similar JDM bikes we can mention Honda Hornet 250, and Honda Jade 250.

Engine, Power output, Top speed
First, let’s talk about the engine, this bike is equipped with a 249cc Liquid-cooled 4-stroke 16-valve DOHC in-line 4-cylinder engine. This engine can produce the max output that is possible from a 250cc four-stroke engine. Because this engine is equipped with DOHC (Dual overhead camshaft) technology it can be more costly than other bikes in this engine capacity.
This bike can produce up to 45BHP, and can reach 0-100 between 5-6 seconds. If we talk about top speed this bike can reach up to 180kmph and sometimes even more than that. However, CBR 250 Fireblade model which was produced after 1994 was capped at 40BHP due to legal reasons.
As most of the 250cc bikes that were produced by Honda at that time this bike is also equipped with a liquid cooling system. Because this engine is 4 cylinders and 16 valves compared to other 200cc – 250cc bikes this engine produced more heat, for this all, liquid cooling was the most suitable cooling system. Cons of having a liquid cooling system are that its so much costly than maintaining an air-cooled engine and also in case of an accident these parts were very costly and hard to replace.
Gear, Clutch, fuel supply
Honda CBR250RR is equipped with a six-speed gearbox and a Wet multiple plate coil springs clutch. With this clutch we can change gears in any speed without any noise. Fuel supply of this bike is equipped with a 29mm Keihin Carburetor. We can expect up to 18-25 kmpl fuel efficiency with a 13-litter fuel tank and 1.6 litter reserve capacity.
If we talk about the design of this bike, we can clearly see that Honda focused more on rider than the passenger. The body fairing and all are designed to achieve high speeds while maintaining stability. If you’re always riding with a passenger this is not the bike for you. Because the passenger seat is located high and the foot pegs are also located high. If you always ride with a passenger Honda Hornet 250 will match your requirements better.
Full body kit of this bike is manufactured with plastic and fiber. Because this bike was last manufactured in 1999 there is no original body kits available in the market. If somehow you get into an accident or broke your body kit you will have to make a fiberglass body kit or will have to settle for a Chinese body kit.
This bike is equipped with an analogue meter panel. This is common for a bike that was built in the 90s. this meter panel is equipped with RPM, speed ODO, trip and temperature gauges.
As the head light Honda has used two 60/35-watt halogen lamp lights and 18/5-watt tail lights with 15-watt signal lights.
With clip-on handle bars rider can achieve high speeds while maintaining stability with a sporty riding position, but the con is its so hard to ride this bike on traffic riding with the riding position and turning circle is very small.
Honda has equipped CBR250RR with a diamond aluminium frame, which helps the rider with stability at high speeds. When we try to hit RPM red line there is no any vibration or extra noise. But when we ride the bike at red line RPM there is a slight vibration from the body kit and handlebars.
Suspension, breaks, tyres
Honda CBR250RR is equipped with front 37mm Conventional Forks and rear mono shocks. These suspensions are commonly used in bikes that were manufactured at that time.
If we talk about breaking Honda has equipped 275mm double disc brakes with dual-piston nisin callipers. In recent days front double discs are only equipped in high-capacity bikes only, but with the 4cylinder 250cc engine double discs are a must and with these breaks, riders can ride at top speed without thinking about breaks. With double disks, we get safety and a sporty premium look. Rear brakes are equipped with 220mm single disc with a single nisin piston calliper.
Honda has equipped this bike with 110/70 front tyres and 140/60 rear tyres with 17-inch alloy wheels.
At last, this bike is now most suitable as a beginner bike or a collectable, because most of the bikes that are on the market are older than 20 years and to find a bike without any errors is so hard.
