Q. Is this bike good for highway riding for touring around 100km, what about its riding comfort if we want to compare its to RE Bullet 350 not in terms of power or torque just i want to compare in terms of comfort and technology - FZ 25?

Comfort is much better in 350 as the seating position of FZ is inspired by street fighter bikes.In figures torque is better in 350 but due its weight you can't feel that torque whereas in FZ you can feel it. Anyways after some time of usage you find yourself comfortable on FZ. And power is better in FZ.

Two bikes r so comfortable but bullet 350 is more torque & power bater than fz 25 because engine is 100cc more than fz 25

Its very comfortable.
