Q. Can Royal Enfield Thunderbird 350 run on highway without any stoppage?

Keep your speed around 80 KMPH. Beyond that vibrations can be worrying. For smooth ride, may cruise @ 70-80. It has a 20 litre tank, though it is advisable to fill it halfway only as per many. I got mileage of 42 KM per litre on highway. So, running without stoppage will not be an issue for the machine. And believe me, it can run.

Yes . It won’t stop on the highway but you would feel very high vibrations on way due to its heavy built engine. Although, you feel better comfortable and riding quality .

It depends on the Driver, its a beast which suits for long rides.yes it runs even longer distance with out stop .Speed from 60 in city cruising and 80 in highway crusing gives a good , comfortable, mileagable rides..
