2014-2022 Kawasaki Ultra 260X Review

The Kawasaki Ultra 260X was a member of Kawasaki’s high-end Ultra family.

This line was released in 2007 with the introduction of the supercharged Ultra 250X and its smaller brother, the non-supercharged Ultra LX.

The platform that this series utilized was carried over to the Ultra 300X and LX, and finally to the Ultra 310 series.

Although they featured the same base engine, the engine power of supercharged Ultras was boosted several times:

  • 2007: 250 HP
  • 2009: 260 HP
  • 2011: 300 HP
  • 2014: 310 HP
The Ultra 260X hit the marketplace in 2009 and remained in production through 2011.

Let’s get down to the nitty-gritty and talk about this ski in detail!

Kawasaki Ultra 260X Hull and Top Deck

The Kawasaki Ultra 260X inherited its 22.5-degree Ultra platform from its predecessor the Ultra 250X.

This fiberglass Kawasaki Jet Ski hull measured 132.7 inches in length, 47 inches in width, and 45.3 inches in height. Compared to competitor skis, this ski was significantly larger and heavier.

Its robust top deck offered industry-leading capacities, including a 20.6-gallon gas tank, and an overall storage capacity of 60 gallons. The latter included a glovebox with a removable drink holder, a 53-gallon bow storage, and a smaller storage bin under the saddle.

What’s more, there was some additional storage space below the lift-out bucket of the front storage.

The curb weight of the ski was no less than 1063 pounds.

Kawasaki Ultra 260X Engine and Propulsion

The power source of the Kawasaki Ultra 260X was a 4-stroke, 1498cc, DOHC, 4-valve, inline 4-cylinder Kawasaki marine engine, which produced 260 HP at 7,750 RPM.

This power mill was derived from the ZX-14R Ninja motorcycle but was heavily redesigned for marine use.

It featured a lot of innovative systems including digital fuel injection, semi-dry-sump lubrication, open-loop cooling system, electric start, and a direct drive system.Its performance was boosted by a roots-type Eaton TVS (Twin Vortices Series) supercharger, featuring a belt-drive system and a large intercooler.

As the name suggests, the engine of the Ultra 260X offered 10 HP more than the predecessor 250X. Are you wondering where this 10 HP increase came from?

In a nutshell, the key upgrades of the new 260 HP engine configurations were as follows:

  • Revised pistons
  • Raised compression ratio (from 7.8:1 to 8.4:1)
  • New intake
  • New exhaust camshafts with more lift
  • Stronger engine cases
  • Upgraded cooling system
The revamped cooling system was tuned to help the engine run at higher temperatures in cold water.

This was a game changer since in the 250X engine the unburned fuel was prone to seeping past the rings and accumulating in the sump.

Besides these engine tweaks, the 155mm impeller was slightly redesigned as well to keep up with the increased power.

This 3-blade, stainless steel, oval-edge impeller was nestled in a standard axial-flow, single-stage jet pump, producing a maximum thrust of 1,585 pounds.

Kawasaki Ultra 260X Features

The standard features of the Kawasaki Ultra 260X and 300LX were as follows:

  • LCD dashboard
  • Kawasaki Smart Steering system (KSS)
  • Smart Learning Operation (SLO) mode
  • Mechanical reverse
  • 6-gallon fuel tank
  • Fly-by-wire throttle
  • Cruise control
  • Riding modes
  • 5-way adjustable handlebars
  • 56-gallon front storage compartment
  • Glove box with removable drink holder
  • Under-seat storage case
  • Variable trim system
  • Tool kit (stored in the back of the rear seat)
  • Rear grab handle
  • Reboarding step
  • Mooring cleats
  • Tow hook
  • Sponsons
  • Deck mat
Both skis were equipped with an innovative multifunction display, of which the key features were as follows:

  • Analog tachometer
  • Speedometer
  • Maximum speed & engine RPM
  • Boost meter
  • Fuel level gauge
  • Low battery voltage indicator
  • FI indicator
  • Immobilizer indicator
  • Engine oil pressure indicator
  • Engine cooling water temperature indicator
  • Operating mode indicator
  • LED warning light
  • Clock
  • Time meter
  • Trip meter
  • Hour meter
There’s no question that the biggest flaw of the Ultra 260X was its outdated mechanical reverse.

While Sea-Doo had already been equipping its high-end skis with the innovative electric brake and reverse system (iBR) from 2009 onwards, Kawasaki Jet Skis lacked this important feature.

They were only engineered with a simple cable-controlled reverse bucket, which offered less comfort and safety than Sea-Doo’s iBR.

The main drawback of Kawasaki’s mechanical reverse was that it couldn’t be used for braking

Kawasaki Ultra 260X Performance Handling

Thanks to its deep-V platform, the 260X offered great overall handling and superior straight-line tracking.

Its deep keel cut the chop with ease, so the 260X ensured industry-leading rough water performance. So, it was no surprise when the Ultra series won several endurance PWC championships.

Regarding performance numbers, the Ultra 260X offered a top speed of 67 mph and did the 0-30 run in less than two seconds.

The claimed fuel economy of the Ultra 260X was a whopping 19.7 GPH at full speed, which translated to a cruising range of 65.3 miles or a playtime of 59 minutes.

Due to its great stability and roomy swim platform, the 260X was ideal for engaging in various water activities like wakeboarding, touring, and even fishing.

The riding position could be easily adjusted with its 5-position adjustable handlebars.

Its innovative “Kawasaki Smart Steering (KSS)” off-throttle steering assist system and the Smart Learning Operation (SLO) key were game changers for novice riders. The latter was a special SLO ignition key that restricted the engine power, so riding it would be safer.

The Kawasaki Ultra 260X had been manufactured for two years without any significant changes before it was replaced by the more advanced Ultra 300 series in 2011.
