It contains the intake valve of 10.5mm and exhaust valve of 9.4mm, which is bigger as compared to the previous 2017 Honda CRF250R model. This increment in the size of valves gives more power and best performance. The use of larger valve diameter of 33mm of intakes and 26mm of exhaust ensure the better performance. The DOHC design engine with big-bore and short-stroke provides an additional 900 RPM. The peak power and peak torque of an engine are also increased by 2000 RPM. The design of engine ensures the peak power and peak torque.
The new 2018 CRF250R Honda Dirt Motorcycle features the low rear shock providing the lower center of gravity as well as maximum chassis stability. The use of Showa fork of 49mm features the conventional spring design, which helps in increasing of front-suspension precision. The piston diameter of 39mm and rod diameter of 25mm guarantees an optimal feel. The shortening of swingarm makes the chassis lighter plus it ensures the better rear-wheel traction. Its design reduces the unsprung mass. The Honda bike features the latest block-on-block design technology MX3S tires. These tires give an excellent feedback and grip. The new large front-disc brake of 260mm ensure the strong stopping force. The rear and front brake-disc guards are the part of this package as well.
The new 2018 CRF250R Honda Dirt Motorcycle features the double-overhead-cam (DOHC) engine layout with the unique finger-follower rocker design. The use of new intake tract, bore and stroke and piston ensure the more power and best performance. This engine features the lightweight titanium intake and exhaust valve. The valve angle is reduced to the super-narrow 20.5-degree. The ovalized valve springs and the long-wearing Diamond-Like Carbon (DLC) treated finger rockers complete this package. The DOHC cylinder-head design allows the Honda’s engineers to straighten the intake and exhaust tracts. The intake is shorter and straight and the exhaust flows more efficiently too. This engine ensures more response and power. The larger bore of 79mm and shorter stroke of 50.9mm ensures engineers have created the high-revving engine with the more room for larger valves. The dual-exhaust system is very light, compact and it is positioned close and low in the frame. It has low weights at the rear end plus it brings more mass to the center of bike for better handling. It provides more airflow for more power. This dirt bike features an efficient electric starter, which ensures the engine starting in all conditions. The intake head and the exhaust system is carefully designed for efficient air flow. The bridged-box piston design is newly developed. It is very strong but light in weight providing more power and ultimate performance. There is “H” cross-section design on the crankshaft profile. This design enhances the strength and cuts the weights. This bike provides more power and torque than 2018 Honda CRF150R. The dual exhaust pipes feature the large-radius bends exits from the head into the mufflers with no abrupt angle changes. The engine maintains the tuned exhaust length, which is the key for more power. The low mass of pipers with twin-cylinder design optimizes its center of gravity. The new clutch design with the new clutch basket and clutch plates uses two different types of friction material. The Lithium-Iron-Phosphate better is used as a power source, which is light and high performing. It weighs less than the conventional lead-acid battery. The simple handlebar-mounted button allows the rider to change the engine power delivery. There are three different engine modes i.e. Standard, Smooth and Aggressive. The new titanium fuel tank is very strong and light. It is thinner than the previous model and help in a centralization of fuel. There is a special oil scavenger pump which is located deep in an engine. It helps to keep the overall design compact. The new shared engine/transmission oiling design makes the engine more compact.

The use of in molded graphics not look gives awesome look but it also stays much longer. The new subframe is very light in weight and contributes in achieving of the lower center of gravity. The flat seat and tank junction including the titanium fuel tank make it easier for the rider to move forward and backward for better control.
