Royal Enfield Classic 350 is the bike which require time to time maintenance. Its alloy wheels require cleansing within 2-3 months. As its interior is continuously revolving due to this there may be chance of slow down of wheel revolution or they can be seized. So, maintenance is required. Other reason is that there is no fuel indicator on the bike. The user came to know only if it comes on reserve. And it consume too much fuel rather than normal bike.
