CRUZTOOLS TIRE GAUGE
Reduce fuel consumption and tire wear and improve your bike's handling by keeping your tires properly inflated. CruzTOOLS has two ways to keep tabs on your pressure: a pocket-sized digital unit for $18 (batteries included) and a dial-type gauge with a 12-inch hose, brass fittings, and a protective rubber cover for $20.
PIPERCROSS AIR FILTER
Save money and reduce waste with a Pipercross air filter. Pipercross filters start at $50 and are infinitely washable and reusable. They even come with a lifetime warranty. The filters are made in the UK and use a layered, multi-density foam element that's said to offer increased protection and improved airflow compared to OE units.
SCOTTS OIL FILTER
This is the last filter you'll ever need to buy for your bike. Scotts reusable oil filters are made in the USA and feature machined-aluminum housings and medical-grade stainless-steel filter cloth, as well as magnets for pre-filtration purposes. Scotts filters are available for most street, dirt, and automotive applications and range in price from $70–$170.
MATRIX M28 OIL PAN
This handy oil pan makes it easier to collect, store, and transport used motor oil. The Matrix M28 oil pan has a 10-quart capacity, a low-profile design that fits easily under any bike, and stores upright to save space. It's made in the USA, from recycled plastic, nonetheless. Pick one up for $20 with free shipping.
VALVOLINE NEXTGEN OIL
The concept sounds questionable, but the science is sound: Valvoline's NextGen semi-synthetic motor oil is made from 50 percent used oil and exceeds all common SAE and API standards. Valvoline filters and then re-refines used motor oil, which saves energy and resources. Buy it by the quart for $9 a bottle. (The bottle is made from 50 percent recycled content, too.)
