!!!!!KEEP IT SMOKING!!!!!
There is nothing as horrible as an LC or POWER-VALVE with chronic tyre mismatch. I bought one once with a Pirelli Demon 130/90 rear and an Avon Roadrunner 90/90 front. It weaved from 10mph and just about threw me off at 80 on the ride home . Needless to say, they where replaced after I did it up. Oversize tyres slow down cornering speed and the unsprung weight on the back will slow down the bike to, even if the tyres are a match pair. I’d pick the Bridstones or Pirelli then Metzellers . [Still not much by today’s standards]
