Race DFI Ski

The lightest jet-ski in the world at 24.9 kg — fits in a car trunk, carries with one hand, and rides with motorcycle-like control on the handlebar. Take the bar off and it's a hands-free surfboard.

The lightest jet-ski

"Ultimate toy for handlebar lovers!" It's ridden upright on the bar, with control that feels "like a motorcycle" — and it's genuinely portable: 24.9 kg, fits in a car trunk, and carries with one hand.

The handlebar comes off in minutes to ride it as a hands-free surfboard, the built-in alternator keeps the battery topped up, and JETSURF rates the controls as "suitable for all skill levels."

  • NG 100 DFI engine — 100 cc two-stroke digital fuel injection

Features

Weight

24.9 kg — lightest jet-ski

JETSURF's lightest handlebar board, and the lightest jet-ski on the market.

Transport

Fits in a car trunk

Short enough and light enough to load into a car boot — no trailer, no roof rack.

Transport

One-person carry

Carry it to the water and back by yourself.

Setup

Convertible to surfboard

Take the handlebar off and ride it as a hands-free surfboard, or put it back for handlebar riding — swap in minutes.

Power

Built-in alternator

Charges the electronics battery while you ride, so it never has to be charged between sessions.

Engine

NG 100 DFI engine

100 cc two-stroke with digital fuel injection and an aluminium exhaust.

Fit

Adjustable handlebar length

Set the handlebar reach for your height and stance in seconds.

Comfort

Protective foam pad

Foam pad on the handlebar to cushion body contact with the bar and the odd knock.

Easy-to-use controls

Simple throttle and controls that read clearly on the water — part of why it suits all skill levels.

Deck

Maintaining the Race DFI Ski

A DFI petrol board, so the petrol maintenance library covers it end to end — the after-ride flush, spark plug and DFI service, the aluminium exhaust, and a full engine rebuild if it comes to that. The built-in alternator means less battery fuss than the older boards.

Owner’s manual: Part A – operation & maintenance (PDF) · Part B – specs (PDF) · Handlepole & handlebar setup (PDF)

  • After every ride — rinse, flush the cooling system, dry the engine bay
  • Every 6–10 hours — spark plug and main bearing check
  • 50 hours / 12 months — full shop service
  • Before every ride — the six-point check
