New: Venhill 888 fast-action twistgrips

CONTROL specialist Venhill has launched its new 888 range of bike-specific fast action twistgrips.  Supplied complete with the company's top of the range Featherlight cables, the kits are designed for a straightforward replacement of the factory-fitted equipment.  Bike-specific kits are now available for the Honda CBR600F, Kawasaki ZX-6R/ZX-10R, Suzuki GSX-R600/750, Triumph 675 Daytona and Yamaha R1/R6, among others, with prices from £105. Here's Venhill's description of the new product: "Manufactured with a robust CNC machined alloy body, the 888 fast action twistgrip provides a choice of two settings and is supplied with two rotors so that riders can select the throttle action that best suits the riding conditions.  Settings can be changed swiftly by undoing the two set screws securing the throttle body and changing the rotor. On the fastest setting there is 80° of rotation, (taking up 36mm of the cable), which is typically 45% faster than 'standard' throttles.
