World first test: Motus MST

Published: 30 October 2016

'It's a hugely entertaining first attempt’ 

Tucked away in an indus- trial unit in Birmingham, Alabama is America’s most intriguing motorcycle manu- facturer. Instead of build- ing their new bike around a V-twin like Harley, Indian, Buell, Victory and almost everyone else on that continent, Motus have produced a 165bhp 1650cc V4.

It’s an extraordinary creation, and not just because it blends an old-style pushrod motor with cutting-edge fly- by-wire electronics and multi-point fuel injection. No, the real revelation is the power delivery.

TOP STORIES

At tickover the off-beat, lumpy shudder is unlike anything else. Where Honda’s velvety VFRs hums, this big- bang V4 grumbles in a far more sinister fashion. You get the sense that, like a dragster warming up, big things are about to happen.

And they do. The low-rpm torque is colossal at 2500rpm it makes more than a Suzuki GSX-R1000 does at its peak, and it keeps rising until 5000rpm. What this means is if you snap the throttle open at anything above ticko- ver the front wheel will lift and 265kg of sports-tourer will start to pivot about the rear wheel. At only margin- ally higher rpms you get acceleration that the world’s fastest sportsbikes only beat when they’re heading to- wards their stratospheric redlines. The MST’s six-speed gearbox is OK - think

BMW GS rather than anything slicker but you barely need it once moving. Sticking it in top will let you ride at a mighty pace on anything from B-roads to motorways.

Though the torque is the highlight, there’s plenty of power if you do rev it out. To disprove the doubters who thought a push-rod V4 could never be properly fast, Motus took an MST-R (the slightly hotter version of the stand- ard bike) to Bonneville and managed 168.69mph. No wonder the company is doing a roaring trade selling its engine to everyone from kit car builders to jet boat manufacturers.

When the initial thrill of twisting the throttle and flinging yourself at the horizon subsides, it’s possible to appreciate the MST’s other charms. The Sargent saddle is large and comfortable and the riding position remarkably upright as tested - the bars are fully adjustable so you can choose whether you sit up straight or hunker down. The screen is adjustable too and though no BMW RT, it deflects most of the breeze from your head and shoulders.

As you’d expect, the MST’s designer Brian Case scribbled down the chassis geometry he wanted at the beginning of the project. Remarkably, it remained unchanged throughout the entire development process and you can see why: the MST steers neutrally and manages to feel surprising light on its feet for such a big machine, possibly because of the centralised mass of that engine (no heavy camshafts on top of the cylinders remember). 

‘At 2500rpm it makes more torque than a GSX-R1000 does at its peak’ 
The suspension and brakes are high- spec Öhlins and Brembo, so there are no surprises in that department, and the ride errs on the sporty side without rattling your teeth on poor surfaces. In fact, the only chassis niggle is the woeful lack of steering lock. Overall, the MST is a remarkable effort and the fact that it’s made by a company with nine employees makes it all the more so. Perhaps the machine’s only downside is the complete absence of electronic rider aids, which in turn prevents it coming to Europe because of the Euro4 requirement for all bikes to have ABS from next year. We think that’s a shame because if you’re not short of cash and want a characterful sports-tourer, the Motus MST is well- nigh perfect.

Who are Motus?

America’s newest bike manufacturer was started by ex- Confederate designer Brian Case and his business partner Lee Conn in 2007. They wanted to build a sports-tourer that wasn’t a V-twin and settled on half a Chevy V8. They build five bikes per week.
