It's easy to find the helmet size to fit you. Motorcycle helmets should fit snugly on your head even if you've got big hair. Ideally pressure should feel firm and even all over.
	To find the right helmet size, measure all the way around your head at the widest part from the front of your forehead right around the back of your head and back to the front again, keep the tape measure above your ears as shown (F) and make sure it feels firm but not overtight or too loose - all measurements in centimetres (CMs).

It's easy to find the right shoe size, just follow the steps below and have fun. Remember to wear your normal riding socks and if you're an all-year-round type you might want to make a bit of allowance for the winter woollies.
	Sole Measurement: Place both feet (in your normal riding socks) on a piece of paper and carefully draw the outline of each foot. Make sure you keep the pen pointing straight down to get a true outline! Then measure the lengths of both outlines from the top edge of your big toes to the back edge of your heel. If your two feet measure differently, take the longer of the two measurements and that's your size - all measurements in centimetres (cms).

It's easy to find the glove size to fit you, but remember if you are planning to wear undergloves as well you may want to go up a size for comfort:
	To find your glove size, clench your hand slightly and measure your hand in a loop as shown, at the fullest part of your palm (H), bring the tape measure all the way round until it joins back at the beginning. If you fall in between sizes, choose the larger one - all measurements in centimetres (CMs)
