Its not fair. You cant steal the thunder of RX115 with a CB180.
CB180 is a custom built time machine. Engine kisi bike ka..... frame kisi aur ka. Trail engine like these XL180 have immense torque to handle a big chunky rear tyre and rough terrain. Bolt it on a CB-125 or CB100 frame it the combination becomes a bike of its own class. A CB180 feels like its skipping the road in big lengths........Thats bcoz of the torque.
FC if your CB125 is faster than a RX115....... Im pretty sure something fishy is going on inside that stock looking engine......... Seriously dude....is it really stock?
