SRX 120

2018 Snowmobiles

It's great - just like Dad's!

Cute it may be, but this is no toy. The SRX 120 looks, feels and rides much like a full-size Yamaha, so it’s the perfect way to introduce our younger generation to the thrills and the fun of snowmobiling.

They’ll be learning too, because from its compact, smooth-running OHV engine to its easily-handled brakes, steering, suspension and track, this smart, sporty-looking machine shares the mechanical principles of its larger siblings and is every inch a ‘real’ snowmobile. So when the time arrives, the transition to their own full-size Yamaha will come easily and naturally.

In the meantime, the SRX 120 promises you real family fun out on the snow – and won’t they just love it?

Yamaha 4-stroke OHV engine

The sporty-sounding 123cc OHV engine of the SRX 120, with its reliable transistorised ignition is compact and well balanced within the body of the machine - just like a full-size model - and it's a smooth-running, quiet and economical Yamaha 4-stroke too, so reliability is assured. Top speed is limited to around 13 km/h.

Adjustable rear suspension

The rear suspension gives a comfortable ride and is adjustable over a range of 3 settings so that as a child grows, the SRX 120 can 'grow' too! Over bumpy snow, the frame sliding mechanism allows a see-saw motion for a smoother ride, while its 100mm stroke length gives the SRX 120 a level of suspension performance comparable to a full-size model.

Double wishbone front suspension

The SRX 120 is designed to familiarise young riders with the enjoyment that comes from having control over their machine. So the all-important front suspension design is essentially no different to a full-size Yamaha snowmobile. Its smooth stroke and minimal change in camber angle offer nimble cornering with least force on the handlebars.

Camoplast® track design

Like we said, although the SRX 120 is made for children, it's no toy, so we've given it a thoroughly grown-up Camoplast track for good grip on the snow. What's more, for maximum traction and minimal understeer in cornering, it has a specially designed lug set (17.5 mm height) and the same track construction as our full-size models.

New body design with special 50th Anniversary graphics

The 2018 model features a new body design, directly descended from the aggressive styling of Dad's Sidewinder and the new seating and handlebar arrangement are designed for simple steering and control, which helps build a young rider's confidence. It even has Yamaha Racing's uber-cool 50th Anniversary graphics scheme.

Comfortable seat and handlebars

For young riders to grow in confidence and gain the most fun from their early snowmobile adventures, the machine's balance, controllability and comfort needs to be every bit as good as a full-size. Which is why the specially designed handlebars and comfortable seat play an important part in making the SRX 120 so easy to control and handle.

Teaching children how to play in the snow

For any child, the thrill of a first solo snowmobile experience is hard to beat - and they'll love the SRX 120 from the moment they fire it up. But so that parents can enjoy it too, we've limited the top speed to around 13 km/h and added a tether switch to stop the engine automatically should the rider part company with the machine.
