Radical Rider Splitboard 4.0

More tail guidance than the Scout: the Rider 4.0 is Radical’s broader all-mountain freeride option. It targets riders looking for a defined edge and support for powerful turns.

Is the Radical Rider Splitboard 4.0 26/27 right for your tours?

Freeride splitters get 3 mm taper, 25 mm setback and a relatively long tail. Spoon nose and spoon tail are part of the current 4.0 shape. Carbon and Kevlar describe construction; with listed weights starting at 3.2 kg, we would not choose it solely on a general lightweight claim.

What should you consider on the ascent?

Camber and firm torsional tuning are part of the concept. A central connection joins the halves and skin holes aid fitting appropriate skins. We have not yet tested how the current 4.0 works on long traverses ourselves.

How do you choose suitable length and width?

Sizes are 160, 164 and 168 cm with 26.2–26.7 cm waists. Radical’s rider range starts at 60 kg for the 160. That does not replace checking boots and stance; an excessively wide deck can become demanding late in the day.

How do boots, bindings and skins work together?

Start by matching boot fit, board width and lateral support. An oversized boot loses support before pressure reaches the edge. For the Radical Rider Splitboard 4.0, we would prioritise heel hold and a highback suited to your weight over choosing the stiffest possible binding. Playful downhill handling need not mean a setup that collapses sideways on a traverse. Practise both touring and riding modes with your actual interface and its specified screws. Plan suitable skins too: length, width and nose and tail fittings need to work together.

Which of our test experiences help you?

We have not yet tested the Radical Rider Splitboard 4.0 ourselves. Our advice uses current manufacturer information and our Gear Guide principles. An older model introduction provides history rather than our own riding test. Manufacturer-shop customer ratings are not used as our editorial scores either.

For a demo, start with a suitable size and your own boots. Check whether you can apply pressure comfortably in slow turns as well as at speed. After a longer climb, consider whether width and flex still feel manageable. A consistent setup is more useful than comparing random boards with very different lengths or stance settings.

What has changed since 25/26 and earlier models?

Radical Snowboards currently includes this model in its regular range. The manufacturer page does not identify a separate technical redesign for 26/27 or a complete change list from 25/26. This page is therefore our guide for the 26/27 season rather than a claim of a newly developed annual model. Compare the actual generation, length, width, hardware and package contents. A new graphic or different price alone does not establish changed tuning.

What is included in the price and what else do you need?

Radical lists the prepared, waxed board with hooks and clips. Add suitable bindings, skins and other equipment. A premium board-only price says little on its own about whether the complete setup is the right investment for you.

Which alternatives should you compare?

Compare Radical Scout Splitboard and Salomon Highpath Split. The riding-style differences are discussed above. Use comparable sizes and your own boots on a demo where possible. A different stance or substantially softer binding can change more than a small dimensional difference between boards. Decide by how well the setup suits your usual tours.

FAQ: What should you know before the first tour?

Does earlier Rider coverage test the 4.0?

No. The earlier model page helps explain its history. Today’s shape, dimensions and hardware apply to the current version. We have not yet tested the Rider 4.0 ourselves and do not invent riding scores for it.

Which size and width suit me?

Sizes are 160, 164 and 168 cm with 26.2–26.7 cm waists. Radical’s rider range starts at 60 kg for the 160. That does not replace checking boots and stance; an excessively wide deck can become demanding late in the day.

Have you tested this model yourselves?
