I have personally used this bike and find it very comfortable. While driving, the bike has a good on road performance.
The road grip is good due to its heavy weight, which also reduces the chances of skidding on curvy roads.
The bike is well balanced and safe for any person to ride. The wide handle bar gives a relaxed feeling.
About bike mileage, my Thunderbird gives around 38 - 42 km/l. It is a very good mileage considering the high amount of torque it produces.
The bike appearance is very attractive and also has a very good pickup. The lower seat height gives better comfort for long drives.
