The YZ125 is available in different model years, including 1980, 1999, 2001, 2002, 2003, and 2025. Yamaha also offers the YZ125X, which is a variation of the YZ125 optimised for Hare Scrambles and GNCC racing.

It is possible to install an electric starter on the YZ125

Yes, it is possible to install an electric starter on the YZ125. There are bolt-on electric starter kits available for the Yamaha YZ125 that include everything you need to convert your motorcycle to electric start, except for the battery. The kit includes a battery box compatible with Antigravity 401 or SC-1 batteries, complete wiring, billet aluminum housing, and solid hardened steel gears.

The installation process involves riveting a new flywheel central section to the OEM magnetic flywheel section and keeping the original ignition. The electric starter dramatically improves the startability of the YZ125, even in challenging conditions, and reduces the need for frequent external charging.

It is important to note that the electric starter kit adds approximately 5 lb to the weight of the motorcycle, and it is recommended to flush the oil after the first ride to eliminate particles generated by the gears' first meshing and break-in.

Additionally, for those with physical limitations, there may be alternative options to consider. For example, modifying the bike with a hand shift mechanism or opting for a different motorcycle model that already has electric start and requires less shifting, such as the KTM 300 XC.

The YZ125 is lightweight, weighing 200 pounds without fuel

The Yamaha YZ125 is an ultra-lightweight dirt bike, weighing just 200 pounds without fuel. This weight is measured on the Dirt Bike Nuclear Scale. Its lightweight nature is one of the reasons why the YZ125 is so popular, with some calling it the most popular motocross bike on earth.

The YZ125's frame is made from an aluminium semi-double cradle, which is engineered to provide the perfect balance of rigidity and flex for competition-ready handling. Its lightweight nature is also due to its two-stroke engine, which is smaller and lighter than a four-stroke engine.

The YZ125's weight compares favourably to other dirt bikes. For example, the 2016 YZ250F weighs 222 pounds, while the YZ450F is 239 pounds. The KTM 125SX is expected to be lighter than the YZ125, but it hasn't yet been weighed.

The YZ125's lightweight design and sophisticated suspension make it a highly capable bike for motocross and other off-road riding. Its weight contributes to its agility and handling, making it a popular choice for riders who want a nimble and responsive bike.

While the YZ125 does not come standard with an electric start, it is possible to modify the bike to include one. Electric starters are available for purchase, and some riders have found creative ways to install them, such as cutting a hole in the ignition cover and using a cordless impact drill.
