KWS Motorsports ran the 2009 Factory Aprilia Millennium Technologies Team in AMA Pro Racing, scoring 2 podium finishes and 7 top five finishes in Daytona Sportbike. We have been developing upgrades and improvements for the RSV4 since 2010 with astonishing results. The RSV4 is a technological tour de force with a 1000cc, quad-cam, 16 valve engine with variable intake tracts and fly-by-wire throttles. The chassis is race spec right out of the box, with an adjustable swing arm pivot, steering head, and motor mounts. KWS now offers a full line of performance parts and upgrades for the fastest Aprilia.
