Questions you may find useful
I am a first-time geared two-wheeler rider. I am an 11th-12th student planning to buy a bike as a birthday gift, and I am deciding between the Jawa 42 FJ and the Yezdi Roadster 2025 model. Which one should I buy? I am 181 cm tall and weigh 82 kg. Also, how should I maintain the bike in terms of cleaning, when should I clean it, and how can I prevent it from rusting?
Both the Jawa 42 FJ and Yezdi Roadster are mechanically very similiar with the only difference being some visual elements and how you sit on the bike. A test ride of both over various road conditions should help you decide which one is the right fit for you. Coming to when to clean your bike, that's a very subjective thing based on where you live and how you store your vehicle. If you have covered parking that protects your bike from dust, then a soap wash once every 10 days to a fortnight should be more than sufficient. If you don't, then you may have to clean it more often. To prevent rusting, try to regularly coat exposed metal parts with some sort of grease and try to keep them under a good-quality bike cover.
