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.

Ben Spies talks MotoGP

TECH 3 Yamaha man Ben Spies gives a fairly in-depth interview about Mugello MotoGP, his championship hopes and his riding style with On The Throttle TV. The multiple AMA superbike champ, who's racing for the first time on many of the MotoGP tracks, reveals he spends most of Friday practice learning the circuit, while others are focusing on set-up and fast lap times. Spies fan or not, it's well worth a watch.

R1 noise, bike porn and a quick lap

Trawling the internet for a sound clip of the Crossplane Crank Yamaha R1 on full chatter, I came across this: a few fast laps on board with New Zealand Superbike racer Tony Rees as he works the CABS Throttle Blipper on his 2011 R1. (Skip to 7:35 for the fast ones.) CABS is a system used by Superbike teams that makes use of the R1’s digitally controlled throttle. When you change up a gear, the bike blips in the perfect amount of revs to save time on track and make downshifts as quick and easy as clutch-less upshifts.
