Can't seem to get a consistent answer to the following two questions. Help req'd please.
1. I've got an RF700 Shoei helmet I bought new in 1997. Haven't used it for 6 years. It's never been damaged or dropped. Should I replace it?
2. Tyres on the bike (Metzelers) have f....all kays on them but also haven't been used for 6 years. BTW, the tyres have been shielded from sunlight for the entire time. They don't seem to be cracked at all and generally look ok. Should I replace them?
Cheers
