The New GROM is on its Way to Japan! More Fun with Both Customization and Sports

2021 HONDA MSX125 GROM

New European specification GROM

Higher engine speed and 5-speed transmission

Recently, the new GROM was officially announced in Thailand and Europe one after another, and expectations for its introduction in Japan are finally rising.

It's no secret that the initial GROM model was launched in 2013, followed by the debut of the current model with minor changes in 2016, making it one of the most popular models in its class. And this new model has undergone its first full model change. First, the exterior has been refined, with a simple, fun retro-pop style. The tank side panels and side covers are now easily removable, making it easier to customize the motorcycle.

The engine was also newly designed with a new bore and stroke. The new engine has a longer stroke of 50.0 mm x 63.1 mm, compared to the previous model's 52.4 mm x 57.9 mm. The compression ratio has also been increased from 9.3 to 10.0. The maximum output and torque are 7.2kW at 7,250rpm and 10.5Nm at 5,500rpm, almost the same level as the previous model (current Japanese specifications are 7.2kW at 7,000rpm and 11.0Nm at 5,250rpm) while still being EURO5 compliant.
The use of PGM-FI gives the engine a high-revving output characteristic.

Of particular note is the change in transmission from a 4-speed to a 5-speed. With this change, I can expect a finer control of the rpm and a higher speed in the high rpm range.

The minimum ground clearance has been increased from 160mm to 180mm, while the seat height has been lowered by 4mm to 761mm. The fuel tank capacity has been increased from 5.5 liters to 6.0 liters, and other minor improvements have been made. The weight was slightly increased by 1.3kg to 103kg.

The MSX125 was previously called the "MSX125" in Europe and Thailand, but for the new model, the name will be standardized to the "GROM" model name worldwide.

At this point, no announcement has been made regarding the Japanese debut of the new model, but judging from what I have seen so far, it should be given almost the same specifications as the Thai and European versions.

Advance Sales of the New GROM Race Base Model

Here comes the good news. Honda Racing (HRC) has announced that it will release a "GROM Race Base Model" in March 2021.

It will be based on the new GROM, with the safety parts not needed for racing removed and HRC kit parts such as the ECU, harness, and various switching switches installed and will be sold at stores as a complete race motorcycle equipped with parts (cowl, footpegs, exhaust system, etc.) developed by HRC service stores.

In addition, the HONDA plans to hold the HRC GROM Cup, a one-make race, at circuits throughout Japan, creating an environment where people can experience the excitement of motorsports.

When you think about it, it makes sense that the new GROM would have a higher-revving engine, a 5-speed transmission, and an easily removable exterior. In other words, along with the fun of customization, the new GROM will further popularize participatory motorsports that can be easily enjoyed as a hobby. I eagerly await its debut in Japan.
