We hired a Thunderbird 350 from SHB. Bike was perfect when we picked it up. Traveled around 2500kms (Delhi - Leh - Delhi) but didn’t face as such problem with bike.
No major Breakdowns, just a Battery issue. It kept draining in 1 or 2 days and that was disgusting.
But the bike was good.No engine related problems. Tyres were good, no punctures during the whole trip.
Even we got pretty good mileage of 40-42kms/litre.
Satisfied :D
