As motorcycle riders, we know very well why keeping your motorcycle tires correctly inflated is not only smart economically (since it saves gasoline), but more importantly, it's a lot safer.
Ideally, you should check your tire pressure every day, since pressure vary depending on the outside temperature, and badly inflated tires can cause serious accidents.
Here's a great Christmas gift for any motorcycle rider. Motoress's tire pressure gauge on a key chain! You can never forget the tire pressure gauge if you put your motorcycle's ignition key on it.
