Product details

"Mud, grease, wet roots, hard-packed, leaf-covered, you name it – these XR4s stick to everything and always tempt me to push harder and harder"

"One of our favourites... Excellent, stable but smooth ride feel, trustworthy all-conditions grip and reasonable roll"

"They roll quickly, are predictable, brake well, provide excellent hold off-camber and are a reasonable weight with ample protection"

"They’ve held up well, excelled in some of the sloppiest conditions I’ve ever ridden in and been both predictable and reliable in all situations"
