As said before , I liked the Ramair , especially as it came as an entire package ! As for solvents or mishandling ? I did take good care of mine and certainly kept chemicals away from it . It is however , very easy to damage . Especially when removing the bear claw . Mine is splitting away from the moulded intake rubbers , as well as breaking down in the foam itself . The pod filters are even more delicate , I did look into these , but it seemed that just cleaning the bike , they would be easy to catch and tear . They seem no more resilient than a bath sponge on a stick !
