37x50x11 mm fork seals, suit Honda MC19 MC22 and others.
There are cheaper fork seals out there, but these are the good stuff - XNBR technology, XNBR is a highly sophisticated carboxylated elastomer, which offers exceptional resistance to abrasion, high temperatures and to the additives found in fork oil.
What does all that mean without the science jargon? These are the fork seals we use on our own road and race bikes, because we don't want to be replacing them all the time if we can help it! 5+ years and counting in one of the race bikes, and still going strong. Cheap seals are a false economy, use the best and save yourself the trouble later on!
