I bought ThunderBird 350 last year in marine-blue colour, performance wise this is a real beast will cruise at 80 line anything but after 90 it will vibrate like hell but as per the saying Royal Enfiled Means Vibrations apart from that this beast is not for cornering only front disk brake, when you are cruising at a high speed to hold the bike is a challenge.
The bottom-line is if you want to roam like a king then this is the choice or else do not go for it as spending 1.5K for 200 Kg not worth it
