If you’re planning on touring for a few days or even a few weeks, then you need to get the right motorcycle for the job. Technically, any type of motorcycle can be used for touring – albeit in a not so comfortable way. Motorcycle manufacturers have designed many different bikes with specific features for use in many different ways. Sport bikes are ideal for going fast on tracks. Scooters and mopeds are mostly for slow, leisurely rides on smooth paved roads. Off-road bikes, on the other hand, ride best on dirt roads. Cruisers are designed for maximum rideability on paved roads, while adventure motorcycles are designed to be both at home either off road or on concrete and asphalt.
Since you have to be bold and adventurous to begin with to become a motorcycle rider, the culture naturally gravitated toward longer distance rides. Bike makers addressed this new activity by manufacturing the best touring motorcycles with functional features to make your long ride better.
Here is the some list you can choose:
BMW Motorrad K 1600 GTL
Honda Gold Wing
Honda Africa Twin
Yamaha Star Venture Transcontinental
Yamaha XT1200Z Super Tenere
Triumph Tiger Explorer XRT
Triumph Tiger 800 XCx
Kawasaki Vulcan 1700 Voyager ABS
Kawasaki Versys
Suzuki V-Strom 1000 ABS
Harley-Davidson Electra Glide
Indian Roadmaster
KTM 1290 Super Duke GT
Ducati Multistrada 1260 Enduro
BMW R1200 GS Adventure
If you have no budget to get one of above mention bikes then go for 150 Suzuki. Honda or Yamaha you can even go on CD-70 as well but not recommended by me at all
