Can I put a wider back tyre in the Jawa 42?

You may go for a big-sized tyre but upsizing the size of a tyre is increasingly becoming an obsession with people to create an added visual appeal to their bike. Moreover, It is advisable to go for an upgrade anywhere between the 3% margin for better performance and handling, increased grip, and visual appeal. Do take note that upsizing the wheels and tyres may decrease the fuel efficiency of the bike and may result in a speedometer error on the bike if upsizing is not correct.
