40.74 km on Water: Modified MX450 Sets New Guinness World Record in China

On 25 October 2026, at the Jinjiang River in Mayang Miao Autonomous County, Huaihua, Hunan Province, Zhang Xue — founder of the motorcycle brand that carries his name — rode a modified MX450 motorcycle a certified 40.74 km across open water without touching land. The Guinness World Records adjudicator on site, Xiong Wen, confirmed the mark for "greatest distance travelled on open water by a modified motorcycle", surpassing the previous record of 31.8 km set by Australian stunt rider Robbie Maddison in 2017.

The run took roughly 32 minutes and covered eight stages with seven turns. It was a record 17 years in the making: in 2009, aged 22, Zhang tried the same stunt in Wuyi, Zhejiang, and fell into the water four times, his best attempt covering just 20 metres.

What the Record Actually Required

The machine was not a boat or a jet ski. It kept the production MX450 frame and powertrain, and the modifications were deliberately non-destructive, bolted on so the bike could be returned to standard specification:

• An amphibious skid kit in 6-series aluminium, split into a front and a rear group. Nothing was cut or welded. The front ski acts as a rudder; the body planes on the surface, generating lift the way a skipping stone does.
• A deep-tread paddle rear tyre, whose rotation at speed provides the forward thrust — the rear wheel is effectively the propeller.
• An enlarged fuel tank, because 32 minutes of continuous wide-open running leaves no margin for a standard tank.
• A fully waterproofed air intake and electrical system, the parts most likely to end a water run in the first thirty seconds.

Reading that list as a parts supplier, it is all wear and consumable hardware: fuel system, filtration, tyres, brakes and fasteners. The engineering that wins a record is the same engineering that decides whether a bike survives a rainy season on a bad road.

Why This Matters Beyond the Stunt

Two things make this commercially relevant for distributors and workshops outside China.

First, the credibility of Chinese motorcycle engineering is shifting. A record like this is a public stress test of chassis stiffness, thermal management, sealing and tolerance control under conditions no laboratory reproduces. Buyers who once treated Chinese parts as a price-only decision are increasingly treating them as a specification decision.

Second, brand visibility drives parts demand with a lag of one to two years. When a Chinese marque becomes a household name in a market, its models enter the used fleet, and the used fleet is where aftermarket volume lives. The same pattern followed Japanese brands in the 1970s and Korean brands in the 2000s.

The Racing Results Behind the Record

The water record did not happen in isolation. In the 2026 WSBK WorldSSP season, Zhang Xue's factory team — competing a full season for the first time — took six race wins and three third places, with rider Valentin Debise finishing runner-up in the championship. In the manufacturers' standings the brand finished third on 310 points, behind Yamaha and Ducati, the first Chinese manufacturer to reach the top three of the class.

For parts buyers, racing is a parts catalogue in disguise. Every season of competition produces a documented list of what breaks, what gets upgraded and what gets replaced on a schedule — and that list eventually reaches the aftermarket as demand.

What Distributors Should Be Stocking

If you serve markets where Chinese commuter and dirt models are already common — West and East Africa, South Asia, Southeast Asia, Latin America — the practical takeaway is unglamorous but useful. Keep depth in the categories that a hard-used bike consumes: carburettors and jets for the carburetted generations still in service, brake pads and discs, clutch friction plates, and shock absorbers. Our complete motorcycle range and carburettor programme cover the models that make up the bulk of that fleet, and the parts finder maps an engine or model to a compatible part in a few steps.

Sourcing is the other half of the story. Records and race results raise the profile of Chinese components, which means more enquiries land on a supplier's desk with a specific requirement rather than a generic one. For buyers who need a part built to their own specification — different venturi size, different friction compound, private-label packaging — our OEM/ODM service handles tooling and validation from sample to shipment.

The Short Version

A rider who failed at 20 metres in 2009 rode 40.74 km on water in 2026 on a motorcycle that kept its original frame and engine. The record belongs to the rider and the team, but the parts list behind it — fuel, filtration, tyres, sealing — is the same list our customers order every week. That is the part of the story worth passing to your own customers.
