AR ver4.2 Frame Kit 265mm pitch

AR ver4.2 Frame Kit

The latest evolution in modern snowscoot frames — for riders who keep pushing further.

Relentless evolution.
A modern snowscoot frame for riders who have already gone deep — and still want more.

As more short-pitch compatible boards become available, including the TORINITY Snowscoot Board Series, the latest SnowbikeTech boards, and JYKK’s newest GT-1 and AK-1 board sets, the AR platform continues to evolve.

Sharper. Faster. Higher. Further.

A cutting-edge frame kit built to turn advanced riding into reality.

Ultra-lightweight, low center of gravity, stable, and with a comfortable riding position.
The latest AR ver4 platform has now been refined even further.

Even though it is a deckless design, the custom mounting holes on the box section allow you to install optional accessories such as the BWS lightweight carbon deck made in Japan and wide step system.

The AR is a limited-production frame kit, made in small numbers each year.
Now, the latest Version 4 has been updated once again.

• An ultra-lightweight frame that made one of the most difficult backcountry descents in snowscoot history possible: Mt. Tsurugi in Tateyama
• Incredible weight: Frame 1.6 kg / Fork 1.1 kg / Total 2.7 kg
  (For reference: G70 wide frame 3.0 kg / fork 1.3 kg / total 4.3 kg)
• A next-generation frame kit with growing presence in Japan’s freestyle contests, technique competitions, and slalom events
• Outstanding riding performance that pushes the unique possibilities of snowscoot construction — handlebars with two boards beneath you

Built on the hugely popular AR ver4, which has sold out repeatedly with every arrival, the AR ver4.2 represents the next step in nonstop development.

What’s New on AR ver4.2

• Ultra-light custom fork plate, further shaved down while still maintaining SAS compatibility
• Multiple board-mounting slit positions to increase usable board flex range
• 2 cm longer fork steerer column for taller riders and more setup flexibility
• Further weight reduction through cut-outs in the rear board mounting box
• Custom holes for optional carbon deck installation
• In addition to the AR’s signature lightweight raw clear finish, a limited Gloss Black color is now available
• Ultra-light construction makes it possible to build a 7 kg range snowscoot, depending on parts selection

Limited Edition / Advanced Design

A limited edition frame that incorporates the latest ideas in snowscoot design:

• Deckless
• Tailless
• Short-pitch board mounting

This is a cutting-edge kit made for dedicated snowscoot riders.
Please note that compatible boards are limited, and the frame requires a build concept different from conventional snowscoot frames.

Geometry and Ride Feel

The 69° head angle provides quick handling and easy maneuverability.
The fork legs are 1 cm lower than the racing-oriented Style-R, contributing to both stability and all-terrain control.
The unique top tube welding position allows for a low center of gravity, while fully utilizing the curve of the top tube for a freer, more expressive riding style.

On ver4.2, the head section has been raised further, and the bent top tube improves knee clearance during turns, making it easier to express your style in both riding and tricks.

Depending on your setup, the AR can be built anywhere from:

• a super-light, low center of gravity setup comparable to the Style-R
  to
• a more relaxed riding position closer to the Style-A

Once you experience the planted, ultra-stable feeling created by the short fork legs, it is hard to go back.

SAS System / Easy Board Changes

The AR features JYKK’s unique SAS quick board attachment system, a new mechanism only possible from the JYKK snowscoot factory.
Combined with the deckless concept, board changes and maintenance become much easier.

While overall frame length remains in a basic, practical range, the complete removal of the deck plate and tail pipe results in major weight savings.

The board mounting boxes welded under the frame deck are positioned differently from a standard snowscoot:

• the front rear-box is mounted 4 cm farther back
• the rear rear-box is mounted 8 cm farther forward

This creates a uniquely deep and lively board flex that feels closer to skis or a snowboard.

If you can fully use the torsion and flex characteristics created by the short-pitch setup, the pressure and engagement you can carve into the snow during turns is among the very best.

On ver4.2, slit-style insert holes have also been added to the front fork plate, allowing the front board to be mounted at an even tighter pitch depending on conditions and riding style.

AR ver4.2 is designed to bring out the full performance of both your riding and your boards in every situation.

Enjoy a highly refined modern riding style built around thoroughly developed free-riding geometry.
