It is curious what some small start-ups like the Californian Volojet invent. If not, take a look at their Tomcat kit designed to convert the Zero SR/S and SR/F into a tricycle, very striking. A way to give the Yankee plug-in a more versatile use, without losing the technical qualities that the model offers us in terms of technology.
Volojet Tomcat kit in detail
They have been the colleagues of Visor Down, some of the first to echo this Tomcat Kit from the American company Volojet. We are talking about a structure that can be bolted to the motorcycle that includes a double front suspension. The rear axle is used from the motorcycle, including the subframe, swingarm and rim. Of course, the mechanical part, where I am still present Z-Force 75-10 engine.
This works jointly with a Z-Force battery with 17.3 kWh capacity. As a result we obtain a maximum torque of 190Nm and a final power 83 kWmanaging to catapult Zero’s mounts to the 200km/h. We assume that the increase in weight and loss of aerodynamic efficiency resulting from the attachment of the Tomcat kit will reduce the final performance figures.
On the Volojet website they explain, referring to the Tomcat kit, that: “turns any Zero S-line motorcycle into a three-wheeled motorcycle with a comfortable recumbent seat and track-ready handling. “It is a class leader, outperforming the competition in an eco-friendly, guilt-free way and made with low environmental impact practices.”
They also mention the final autonomy offered by their tricycle, with a figure approved on an urban circuit. around 280 kilometers. There is no talk of pure performance or efficiency data when it comes to riding on the open road. What we do know is that being able to have one of these Tomcat kits mounted on our Zero SR/S or SR/F, has an approximate cost of about 20,000 euros in exchange.
To this price we must add the cost of the motorcycle, and we must wait between 3 and 6 months so that Volojet does not deliver it. The brand also explains that the client can choose key aspects of the project, such as the color or the configuration of the suspensions.
If at this point you have warmed up to the topic, you can check all the details by visiting the brand’s official website.
