Cormac's Tech Shots From Jerez: Holeshot Devices Close Up And In The Flesh For Subscribers

The Ducati left handlebar up close: On the top yoke, the front and rear holeshot device switches, on the handlebar, the red, yellow, and green buttons for the electronics, and a lockout lever for the 'shapeshifter' or ride height lowering device

The Ducati seen from the right: on the handlebar, the pit lane limiter at the top, the neutral engagement lever at the bottom. Holeshot device butterfly switches on the top yoke, and the electronics buttons and lockout for the shapeshifter on the left

A better view of the holeshot device butterfly switches. The F and R are self-explanatory. And the rider-facing camera is also visible on the top of the dash.

Maverick Viñales' Yamaha M1 is fired up. Note the torque sensor on the output shaft - used during practice and testing to work on torque maps and engine braking settings

Sensors galore on the front wheel of the Aprilia. An accelerometer on the brake caliper mount, two speed sensors, and a stroke sensor for the suspension. The Brembo calipers are the new type with extra cooling fins. Note the air blower blowing air into the intake. That helps to cool the electronics mounted under the tank cover

Elegant exhausts with a carbon cover, and an aluminum swingarm. The Suzuki GSX-RR's beauty lies in its simplicity

Like many factories, KTM uses a little trolley for the rear wheel, to allow the bike to be maneuvered more easily (and hidden in the garage more quickly). Carbon swingarm, well-used tire. And the bright red cylinder is the load cell for the quickshifter.

Fabio Quartararo's Yamaha - 3565 is the idle speed. On the right handlebar, the pit lane limiter and engine stop button, as well as the neutral selector lever under the bar. Purple anodised ally head race cover is a 90s throwback

At the back of the Ducati, an accelerometer on the end of the swingarm, 2 speed sensors, and a single brake line to the caliper. No thumb brake nonsense here

The closest most people get to seeing a bike uncovered. Iker Lecuona's KTM RC16 up on stands with no wheels

Aprilia using a carbon swingarm now too, after years of experimenting to get it right

Note the little fuel tank used to warm up the bike. Much easier to handle than the full-sized 22 liter unit used on track.

Another view of the warm up fuel tank. Also clearly visible a large weld at the rear of the swingarm, indicating this is the aluminum version.

The Aprilia handlebar. Clutch lever, and inside, the smaller holeshot/shapeshifter lever, lockwired to prevent it going out of adjustment

A better view, with the front and rear holeshot levers at the front and rear of the clip on. 'Playstation' electronics controller marked with functions: EB = engine brake, TC = traction control

aaahhhhh, so much to see. I didn't know mclaren was supplying sensors! And the carbon weave up close looks so sexy :-)


There is a lot in the cockpit these days. Once it was just a tacho. Then tacho & water temp. Space rockets indeed.

Ducati still have more high technology gadgets than Batman!

No simple linkages with dog bones I could make either. Changeable rear ride height would have definite application on street bikes for short people.

No thumb rear brake for Aleix on the RS-GP. What is the bizzo at the bottom of the Aprilia's radiator? Protection? Temp or flowrate sensor? Transponder? The holeshot device/rear ride height gadget on the Prilla looks complicated. Many little components, fiddly bits & little screws. Franky Morbidelli may not be the only racer to have a problem with this tech. What about those square holes?

McLaren, well spotted daddyrat!

Simple elegant way to secure the wheel covers or disc covers on the front of the RS-GP.

Aluminium swingarms are starting to look old.



That last picture has tread on the Aprilia's rear tire. Is that an intermediate tire? Didn't know those are still available. 

It's the tyres used when the bikes are being transported.

Albesiano intvw? That is all I have seen too. 

But of a rain out, much less to it than hoped. The bike was well fitted to his liking, tried a few basic parts like bodywork options. Hoping for better weather for Day 2. Talks started of a 3rd Test, possibly Misano.
