Honda NSF250R Moto 3

Model Description

NSF250R Moto 3

Padgett’s are the only Official UK distributor for the Honda
HRC NSF250R Moto 3 Machine. 

Power Unit

The 249cc DOHC liquid cooled single cylinder engine is
designed under the concept Light weight, Compact, High-Output and
High-Efficiency.
A higher charging efficiency has been achieved by positioning the intake port
on the front side of the cylinder and the exhaust at the rear. The cylinder has
an inclining angle of 15 degrees to the rear which contributes to the
concentration of mass.
Positioning the balancer-shaft above the crank-shaft has made the unit compact
in overall length.

 

Frame and Body

Although based on the RS125, the frame has a totally revised
stiffness and balance for the new four-stroke unit. The new framework made of
high rigidity, light weight 7000 series pressed aluminum alloy, provides
optimized flexibility and superb riding control.
Revised concentration of mass has resulted in lighter weight and extra room to
position a five liter air-box(excluding the oil catch tank capacity).
