A combination of the original Corbin Gambler and its unique Smuggler storage system , Corbin Saddles has updated its popular Gambler Smuggler seat for the 2021 Sportster S . " Offering a clean look with precision fit to the Sportster ' s chassis , under the passenger seat there ' s a 1.4 liter storage tray for securing small essential
items like wallet , sunglasses or even summer gloves . A wide , ergonomically designed rider platform provides excellent comfort with four vertical inches of lower back support provided by the passenger area . The nose of the seat is sculpted to give good ground reach and fits perfectly to the tank . Passenger seating is neutralized to curb sliding and offers good weight distribution .
" The Gambler mounts directly to the H-D chassis in place of the plastic tail pieces . This allowed us to create a seating position nearly 1.5 inches lower than the stock unit , which gives the rider a much more integrated feeling with the bike . Saddle shaping keeps the seat integrated with the radical streetfighter visuals of the Sportster S ." The Gambler installs by removing the stock tail components and mounting our provided hinge and storage tray . Once installed , the Gambler Smuggler works with the OEM key lock .

M-8 Cooling - Not all Fins are Equal
When it comes to an air-cooled V-twin engine , most of us believe that more fins mean more cooling . However , there is one individual who thinks otherwise - Danny Wilson has turned the orthodoxy on its head . " The large span between the fins on my cylinders creates tunnels for considerably more air movement than is the case with the stock fins . And , if you look at the surface between those fins , there are high and low spots and tool marks . " That uneven surface creates disturbance as the air runs over the surface - the rough surface makes it easier for the air to pull the heat from the aluminum ." Danny ' s unique cylinders are made from billet aluminum with ductile iron liners . The current catalog includes kits that start at 125 cubic inches and go all the way to 159
inches for M-8s . The two smallest kits , the 125 and 129 inches , are designed for installation in 107 and 114 inch M-8s - while the cases stay in the frame . The rest of the kits are aimed at the more serious enthusiasts . These kits include cylinders and a crankshaft and start at 131 cubic inches and go right up to 159 inches . Similar cylinders and kits will soon be available for Twin Cams .
