Sporty Jawa For Daily City Riding

The 42 FJ is my new favorite for city sprints, providing a punchy ride and 26-27 kmpl mileage. Its alloy wheels and tubed tyres are great for peace of mind, while the 41 mm telescopic forks absorb shocks. At 184 kg, it feels planted, and the 178 mm ground clearance handles speedbreakers without scraping.

Quick Urban Roadster Feel

The 334cc liquid-cooled engine gives me a 27 kmpl mileage, and the 178 mm ground clearance is very impressive. Its 790 mm saddle height and 194.6 kg kerb weight make it a very nimble and quick urban roadster. The tubeless tyres on alloy wheels and the LED lighting system add a lot of modern functionality and safety.
