osing the Correct Helmet Size
Helmet fit is critical to helmet protective performance. Different helmets fit differently due to differences in design and construction. The correct helmet size can only be checked and confirmed by physically fitting the helmet to the user. Always try the helmet on in a store, before purchasing it, to be sure you are purchasing the correct sized helmet for you.
Helmet Sizing Information
To achieve proper helmet fitment, begin by finding your head circumference size using the method described. Remember that the helmet size you choose should fit around the crown of your head comfortably with no pressure points. The cheekpads should fit firmly around your face. Once your chin strap is fastened, grab the chin bar of the helmet and move it side to side. Your cheeks should move with the helmet, which should not slide across your face. Different thickness cheekpads can be purchased to obtain the best fit.
Head Measurement Instructions
Wrap a flexible tape measure around your head approximately one inch above the eyebrows and ears. Use this measurement (in either inches or centimeters) to find your helmet size in the chart to the right.

Periodically cleaning of your wheels is necessary to maintain a high luster, especially 24K gold plated wheels these require extra care. Always clean using a mild dish soap and water such as Dawn and a clean microfiber cloth, to clean inside the hub and spokes use a soft horse hair paint brush. NEVER use any harsh cleaning compounds or waxes as the are abrasive and will remove the gold plating. During storage spray a light coating of WD40 on the wheels to prevent rusting.
