Is this a fact with our Triumphs? They don't warrant coolant hoses because they are a consumable?
Personally, I don't think coolant hoses are 'consumable items'. They should be fully warranted during the warranty period. I would liken them to brake lines. They should last the warranty period and then some. Eventually, like everything they will fail/wear out and need replacing but not during the warranty period. Coolant and heater core hoses are covered on autos, why not bikes? Even a spark plug would be covered under warranty if the engine started to missfire. Now brake pads..... that's a consumable.
