Samco Oil Cooler Hoses - SAM-APR-14
Complete fitment list at bottom of this page.
Aprilia uses plenty good enough quality hoses right from the factory (though the one time use hose clamps are frequently disappointing), but these made in the UK hoses from Samco are just that much nicer.
Sold as a LH and RH hose.
The required matching Samco Smooth Band Hose Clamps are sold separately.
