Engine and Transmission The new Honda CBR250R is equipped with 249.4 cc, 4 storke, DOHC, 4valve water cooled engine. With the Bore x stroke size of 76 X 55 mm, CBR250R is able to produce massive power of 26.4 bhp(18.7KW) which peaks @8500 rpm(Electronchandru021y controlled) which makes the power to weight ratio at 163bhp/tonne. You don’t need to engine rev hard as the maximum torque of 22.9Nm produced @7000 rpm. As most of the power available at lower rev the bike will fire at traffic points.
ENGINE
The fuel delivery is handled by Honda’s patented PGM-FI(Programmed Fuel Injection system) which ensures smooth and precise fuel delivery result more power with less fuel consumption. The fuel filter of CBR250R is placed outside the fuel tank to facilitate any intervention and reduce maintenance costs.
The engine mass is kept as low as possible by elimination of unnecessary parts and keeping the moving parts like rod and piston light weight. The friction between engine parts also reduced to significant level which you can feel in engine noise. The Iridium spark plug to squeeze out maximum from every drop of fuel. You don’t need to worry about overheating of engine as liquid cooling system ensures the engine temperature at recommended level.
The Honda CBR250R got six speed gear box with wet multi plate clutch. The short to long gear ratio means you can quickly move into the next gear. The gearbox is designed to exploit the characteristics of the engine at the same time ensuring quicker acceleration and low fuel consumption. The gear shift feel is very smooth and precise.
In order to reduce pollutant discharges, the CBR250R incorporates the latest technology in exhaust. The catalyst metal tri limit emissions of carbon monoxide, nitrogen oxides and hydrocarbons to a minimum. An oxygen sensor placed in the exhaust allows the electronic control unit to further reduce emissions by ensuring the best possible combustion.
Braking Honda is known for making safest vehicle in the world and that’s what Honda proved in case of CBR250R. The new CBR250R got C-ABS(Combined braking system with Anti lock braking system). This is the first time any 250cc bike having feature like C-ABS. The Combined Braking System is known for its effective braking control. It ensures the required combination of front and rear brakes which make sure that the braking torque generated in required manner on front and rear wheel. CBS with ABS(Anti lock braking system) surely going to do wonder’s in braking department.
NB;honda 250 is not a pure sports bike, if u want a sports bike go for a kwasaki ninja or yamahaYZFR 15
