Q. Does it have a bigger wheel size as compared to Honda Grazia, Suzuki Burgman - NTORQ?

Yes, NTORQ has not only bigger tires as compared to Grazia and Burgman, but, it also has fatter tire as compared to them. That is why NTORQ feels way more smoother at higher speeds(above 95 kmph) as compared to both of them. More over, Both Grazia and Burgman has 12 inch at the front and 10 inch at the rear, whereas, NTORQ has 12 inch at both ends.Hope this helps!!!

Yes, All have same Front Wheel Size i.e. 12 Inches but Ntorq Rear Wheel Size is 12 Inches were Burgman and Grazia have 10 Inches Rear Wheel Size. Also Front/Rear Tyre Size of Ntorq is similar 100/80-12 whereas Burgman and Grazia have Front 90/90-12 and Rear 90/100-10.

Yup , it got larger, lighter and thicker tyress of the three scooter in comparison.
