GP1800R HO 2021


Built to conquer. 

The revving power and acceleration come from our latest High Output 1.8-litre four-stroke engine – the largest in the industry – combined with many other innovative features, such as the race-designed top-loader intake grate and ride plate, which further improve acceleration, cornering and rough water hook-up.

The re-designed seat, handlebar shape and sitting position, deeper footwells and lower, more central centre of gravity within the ultra-lightweight body, bring a true leap forward in handling and control. The new Auto-Trim system, with automated launch and cornering control take the GP1800R HO to the next level.

Lightweight hull and body for top performance


Made possible by Yamaha’s unique materials technology, NanoXcel2 is an impressive 18% lighter than our revolutionary NanoXcel – yet just as rigid and strong. It maximises the exciting performance of the new GP1800R HO, helping it deliver its sensational acceleration, even sharper cornering – and more stability at high speed.

New design ergonomics – for superb control


The balance and stability of the new GP has been enhanced by lowering and centralising the centre of gravity, along with the adoption of a new, narrower design for both the seat and the fully adjustable, race-design handlebar. Combined with the new eronomic sitting position and deeper footwells, the result is an amazing new level of rider control.

Race-inspired pump design and intake grate

3 Features

Improving both acceleration and handling, the new pump, impeller and intake grate have been introduced as a result of the excellent results achieved in racing. The extra grip it gives on the water makes for even more responsive and accurate handling in any conditions.

Auto-Trim function with Cornering and Launch control

4 Features

This exclusive, industry-first system offers a fully automatic trim function, which operates independently of the effcient electronic trim control on the handlebar. When engaged, Cornering Control automatically shifts the trim down when decelerating for sharp cornering. Launch Control shifts the trim down to prevent bow rise when accelerating quickly.

RiDE system (Reverse with Intuitive Deceleration Electronics)

5 Features

The revolutionary RiDE system transforms your riding pleasure, bringing a feeling of confidence to every rider... at every level. Simply pull the throttle lever on the right hand-grip to move forwards and accelerate. Pull the lever on the left grip to slow down or to reverse. Yes, it's really that simple.

High Output, 1.8-litre, fourstroke, DOHC, 16V engine

6 Features

The four-cylinder DOHC 1.8-litre, High Output engine is the largest displacement in the industry, yet thanks to our continuous programme of innovation and product improvement, it is extremely compact. The result is astonishing power, acceleration and huge torque, along with clean effciency and economy.
