Like most good quality stuff mate. The pain off the initial cost disappears when the item quietly gets on with its' job with no further input over the years. Did the Armstrong (?) have one?

Onto the electrics / electronics. Part locations got shuffled around to find the best locations. The only fixed locations for some items were the Dash, ECU & the throttle body drive motor. The battery lived up front for a day or so but we decided to build a mount in the original VDue battery location. This mount was fabricated to hold the battery, Mosfet regulator, PMD & a couple of relays.













Up front we mounted the EGT modules, coil driver modules, ECU, TB driver, resistor pack needed to control the oil pump stepper motor and various Motorsport connectors for the front suspension potentiometer, programming & data download.



Once all these locations were fixed in space, the major job of building the electrical loom could be tackled. Glen had a major project in front of him. As usual he did a great job and created a first class result.













The control switches comprised stop / start buttons on the RHS and on the LHS we have traction control + & -, pit lane limiter, Map selector & XXX. There is also a rotary switch that can be assigned various functions such as ignition timing, injector end timing, injector pulse width etc which is used during engine map development. A GPS receiver is also fitted up.





As Trev pointed out, I fitted a thumb brake which subsequently required the fitting of a matching rear brake master cylinder as well.

Clyde fabricated the rear brake calliper mount, wheel speed sensor mounts & the clutch & thumb brake reservoir mounts.

Very nice, that’s a lot of work right there. You must be pleased with how its all coming together

Yes Matty, there was a lot of work in the wiring harness fore sure

Onto some of the associated electronics etc.

The MoTec C185 dash is a data logger and additional electronic control unit as well as a display unit.



The dash is a computer in its’ own right with a powerful mathematics package that can carry out various calculations that the owner may require. The unit can be used in other industries apart from the automotive industry. For example when combined with the GPS function can control / calculate & record various parameters.



We are using only a small percentage of its’ capability on the VDue. An example of one of the controls of the dash is to monitor wheel speeds which are then used to create a traction control system. The dash carries out the calculations & sends instructions to the ECU via Canbus which then alters the throttle position, ignition advance & fuel injection (you can instruct the ECU to control either a single or multiple parameters).

For the traction control we used the phonics & sensors from a Ducati Panigale. Unfortunately the phonics didn’t fit so we used the the design of the Ducati ones & manufactured new ones with suitable mountings.



For the suspension pots, the front one is a straight linear function but the rear suspension pot could not be mounted to give a 1:1 Pot to shock ratio so the dash gets the Pot travel & then converts it to shock travel & also calculates the to rear wheel travel.





Another use is the quick shifter / auto blip for up & down gear shifts.

The QS load cell



The ECU is a MoTec M880 and can be configured to operate most internal combustion engines. 2 stroke, 4 stroke, rotary & diesel across most motorsport or general use. The ECU is also used to control the Power Valve, both when it opens & the rate it opens.

This family of ECUs’ have been superseded by the next generation M1 series.



The PDM manages the electrical side so no fuses are required. you can monitor & log all the power draws going through the PDM so any electrical issues can be identified fairly quickly & where they are occurring.

Once again I have very limited knowledge of the combined systems & Glen is the man in control of all of this. Once the main engine map is built up & the required functions called up in the dash, monitoring of the system is all that is required as alarms & warnings are programmed into the system to show any problems that arise, eg low fuel pressure, battery voltage, charge rate etc.

Onto the brakes.

I went with a pair of BrakeTech Ductile Iron units mounted on 15mm offset Hard anodised carriers. I had to make a pair of 2mm spacers for the discs so to centralise them in the brake callipers.



The callipers are Brembo X99.C4 units with Ferodo ZRAC pads. The caliper is fitted with 4 34mm ventilated Ti pistons and have 4 pads per caliper. I also fitted a Staubli dry break fitting to each caliper





The front brake master cylinder is a Brembo XA7G7GO unit



The Thumb Brake is a Brembo unit that I got in a box of Ducati WSBK parts I bought a few years ago. It feeds the Brembo rear brake master cylinder designed for integrated Thumb brake / foot brake use.



The rear brake caliper is a Brembo unit with 4 24mm Ti pistons. I kept the standard VDue rear disc as it worked with the phonic disc for the traction control.

Love the quality of the parts and work. What a great VDue build. No, make that - what a great build - full stop.

Thanks Bud. These sort of projects tend to take on a life of their own. The plan at the start doesn't bare much resemblance to the finished project due to different parts & opportunities that come along during the build

I’m with Bud on this, the complexity involved makes my head hurt. Really glad there are people of your caliber an talent out there doing these “home” builds.
Just out of interest, is this going to be used in anger or be more of the trophy piece.

Thanks Matty for the comments. At the end of the day I am just the assembler and the real talent lies with the guys who do the creative stuff such as the fabrication, electric/electronic work, engine mods and advice on issues that arise during the build.
Unfortunately there is no class that the bike can compete in under MA classifications but when the dyno work is finished I want to get a talented rider to take if out to finish setting it up both electronically & handling wise as it will be a shame not to do that.
