V2 SuperMoto - Riding Fun Squared
 

All began with the idea of creating a reliable, affordable two-cylinder SuperMoto bike and, as a solid base for this enterprise, we eventually chose the Honda XRV750 AfricaTwin.
SuperMoto is characterised by light, playful handling coupled with explosive power delivery. To transfer these characteristics on to the Honda, massive changes were required.

To significantly reduce weight, the massive front fairing assembly was replaced by a puristic and tiny lamp mask.
The weighty classic instruments and control lights were replaced by a small, modern and multifunctional digital display.
The rear section of the steel frame was cut off and replaced by a lean, more 'sportive' construction.
The heavy 23-Litre steel tank gave way to a specially developed light-weight FRP reservoir, which is shaped extremely narrow yet still holds 16.5 litres of petrol.
Thus the XRV's original 205 kg dry weight could be trimmed to a lean 168 kg.

Top-of-the-range Upsidedown (USD) forks from Marzocchi lead the front wheel. The corresponding milled fork yokes, made of high-strengh aluminium alloy, convince by their rigidity as well as their low weight.
The original braking system has been upgraded with wave discs and stainless steel braided lines.
A 17" Excel rim mounted by stainless steel spokes on the stock hub allow the mounting of the Pirelli Diablo tyre size 120/70, a choice that, together with the improved chassis and the more balanced weight distribution, allows for unimagined riding agility.

Response and wheel travel of the rear suspension were optimised by installing a "HRC" shock absorber by Öhlins. Due to adjustable rebound and compression damping, the driver may tune his preferred setting individually.
Thanks to the wider 17" Excel rim, again on the original wheel hub, a Pirelli Diablo with the dimensions 160/60 can be fitted. This tyre offers a convincing combination between linear traction, extreme cornering ability and good-natured drifting behavior.

In order to elicit more liveliness and top performance from Honda's rather tame V-twin, "Megacycle" camshafts were used in combination with revised intake ducts and an optimised airbox. The carburettors have been reworked and an AfricanQueens "Racing" rear muffler has been installed.
The result: a free-breathing, free-revving power plant, that delivers 75 horsepowers at 7,500 rpm. The torque is spread over a very wide power band with 79 Nm at 5,800 rpm. Overall, the engine gains both, top power output and dynamic performance, without losing its famous sophistication.

The combination of a torsion-free frame with superior chassis components and a lively and powerful engine provides a surprising riding experience, that has little in common with the roots of the vehicle.
We embarked on a quest for the perfect compromise between the agility of a single cylinder and the sophistication of a two cylinder bike.
What we found was brutal riding fun!
