New 2019 Honda Grom Motorcycles / Color Options

It’s that time of the year again guys! Time to start diving into the nitty-gritty details about Honda’s 2020 motorcycle model lineup as we just had a big announcement yesterday that you can check out by Clicking Here. First up for a breakdown on all of the info is the 2020 Honda Grom 125cc motorcycle.

It seems like it was just a couple years ago when Honda released the big announcement in 2013 that they were bring the Grom to the USA for the 2014 model year. I’m about as big of a fan as you could be of the Grom as I broke down and bought a Grom to add to the stable, I put my name down on one the morning Honda made the announcement to dealers before I could even think about getting the chance to throw my leg over one. A lot of people told me I was crazy and that there is no “place” for a 125cc motorcycle here in the USA and that they would be nothing but a huge flop. Well… Fast forward to now and we’re going over the 2020 Grom from Honda. Needless to say, the Grom has turned out to be a huge hit and I couldn’t say thank you enough to Honda for actually giving our side of the pond a chance at this bike as a lot of the cool bikes we don’t ever see and the Grom, known as the MSX125 overseas could’ve been another one of those instances.

  • New Grom Changes… | 2020 Honda Grom VS 2019 Grom Changes? 
    • None. The 2020 Honda Grom is identical in every way to the 2019 model year. I dive more into the history behind the Grom and recent changes etc in the “introduction” section below.

Is the Honda Grom getting stale though in the performance department? Should Honda throw some more horsepower at the 2021 Grom? Should they throw the PCX150 scooter engine in the Grom that bumps its HP up from 9.7 to 14.5? That would be a considerable improvement and they could make a big splash about it with marketing etc. With as hot as the Grom / MSX125 has been, I would say a lot of people would consider jumping into the Grom that haven’t already because of being worried about it’s performance but if you were to make a pretty decent jump in performance like that it might get them on board and even make some existing Grom owners trade their older model in for the 2021 if it made around that 15 horsepower mark. What do you guys think though? I don’t want them to throw some 250cc+ engine in the Grom, it’ll take away some of the fun factor in my opinion but if they did a 150cc setup with at least 15 big strong ponies and that means 20+ horsepower would be easy to attain on a 2021 Grom with just bolt-on performance parts. I’m thinking we’ll see something like this happen in the near future. I could be wrong but I’ve been right a time or two on these things – not to boast or anything haha.

The Grom carries on Honda’s long tradition of creating fun, appealing small-wheeled leisure motorcycles, which started with the original Monkey bike of 1963, and continued with the Dax and the Ape. Since its release in 2013 as a 2014 model, the Grom has earned worldwide popularity, with over 300,000 units sold to date as of this time last year (haven’t received updated figures since then). Its exceptionally fuel-efficient air-cooled 125cc engine, quirky looks and nimble handling have attracted entry-level riders, economy-conscious city commuters, camping vehicle owners, experienced riders, racers and other recreational riders alike. It has also gained popularity as the perfect paddock bike for race teams. Thankfully, Honda didn’t alter what is an already awesome package and make it worse as sometimes we see motorcycle manufacturers hit a home-run with a model, then turn around and do a redesign on the same model that backfired and watered down the bike etc etc.

1. Introduction

Let’s touch a little on the history behind the Honda Grom before we get too deep into what the 2020 Honda Grom offers you. The Honda Grom was originally released as a 2014 model year in August of 2013. The Grom returned in 2015 without any changes. Honda skipped the next production year and did not build a 2016 Grom. Then, Honda attacked the 2017 Grom giving it a sharper new attitude with more of a ‘mini-streetfighter’ feel. The new fuel tank and side panels integrate cleanly to give an edgier outlook; up front a unique, new stacked LED headlight gives the Grom a distinctive, ultra-modern face. The compact, upswept tail unit (with LED taillight), higher passenger seat and short, under-slung exhaust complete the bolder new look. When it comes to the engine, frame etc it all stayed the same so the 2nd-generation Grom wasn’t any faster than the 1st-generation Grom. The 2018 Grom stayed the same as the 2017 Grom but with the addition of ABS (Anti-Lock Brakes) as an option, even the color options were the same. Then we had the 2019 Grom arrive with no mechanical changes but Honda did throw changes in the way of color options. Now, we’re here with the 2020 Grom from Honda and history has repeated itself as the color changes from last year are back again to reign for another model year until we see the 2021 Honda Grom 125.

Easy to use, fun and functional, the original leisure motorcycle was defined by Honda in 1963 with the iconic, small-wheeled Monkey bike and carried on – redefined for each respective generation – with the Dax and Ape. And it’s a formula that still has resonance for a completely new breed of young riders; known as ‘Generation Y’ in the USA, ‘Dek Neaw’ in Thailand and ‘Street-Kei’ in Japan, many of today’s teenagers, having grown up in the borderless, internet age share a culture, fashion and spirit that defies convention.

Instinctively drawn to motorcycling, they need their first two-wheeled transport to be exciting but not unduly challenging, and want it to pack a design that makes them smile. They also have a desire to turn heads and be more than just a little bit different. Plus, given the usual financial pressures of starting out in life, all of this needs to be achieved as economically as possible.

For Honda the early acquisition and introduction to the quality and values of the brand is important – the youthful buyer of a small capacity leisure bike today could very likely be back for something much bigger tomorrow, and lifelong brand loyalty can often result.

To cater specifically for this generation of young riders, in 2013 Honda produced the Grom (also known as the MSX overseas which = Mini Street X-treme 125). A truly global product (and known as the “Grom” in Japan and USA), the Grom has been a hit across the world, in particular in Thailand where over a quarter of a million units have been sold. It’s everything expected of a Honda, in terms of performance, build quality and usability, but also wears a style and exudes an attitude all its own.

2. Model Overview

Manufactured in Thailand the Grom is small enough to be supremely manageable yet also has a fully-fledged feel thanks to some standard sized motorcycle parts. I’ve seen some people be hesitant to purchase because of the country that the Grom is manufactured in, I’ll admit I was worried at first too being that I purchased one of the first Grom models to hit the USA back in 2013 but… You wouldn’t be able to tell the difference when comparing this bike versus lets say a Honda Ruckus that is manufactured in Japan. The build quality, paint quality etc is spot on! It is part mini-bike, part motorcycle with involving performance matched to confident handling and styling that combines a sense of fun with a tough, urban edge.

The Grom’s well-proven and efficient 125cc fuel-injected engine provides smooth torque and power delivery, and also features a motorcycle-style four-speed gearbox and clutch. Complementing the powerplant is a compact chassis that features a sturdy steel frame, inverted front fork, monoshock rear suspension, hydraulic disc brakes front and rear and lightweight 12-inch wheels sporting wide, low profile tires.

Four patents were applied for through the original development of the Grom, focused around the split structure tank cover and frame, proof of just how seriously this bike is taken by Honda. Small it may be, but it in terms of worldwide sales, brand awareness and owner satisfaction, its impact has been large.

3. Key Features

3.1 Chassis and styling

Priorities for the Grom’s chassis were threefold: it needed to provide the base for a practical bike that new riders could use – and park – with ease in an urban environment. But it also needed to be just as useable and enjoyable out-of-town, and also readily accept a pillion.

The comprehensive redesign last year gave the Grom a sharper new attitude with more of a ‘mini-streetfighter’ feel. The new fuel tank and side panels integrate cleanly to give an edgier outlook; up front a unique, new stacked LED headlight gives the Grom a distinctive, ultra-modern face. The compact, upswept tail unit (with LED taillight), higher pillion seat and short, under-slung exhaust complete the bolder new look.

A steel mono-backbone frame has been employed. Its rigid, square-section tube joins the headstock directly to the swingarm pivot plates and every other part in effect hangs visibly from the frame, greatly contributing to the Grom’s minimalist look. Specifically tuned vertical/horizontal rigidity and flex in the swingarm pivot and engine hanger plates provides the perfect balance of comfort and confidence.

The new frame structure also enabled efficient storage of PGM-FI-related components and electrical parts inside the tank cover without reducing fuel capacity 1.45 gallon. Wheelbase is a snug 47.2 inches, with rake and trail of 25⁰ and 3.2 inches and curb weight of 229 lbs (Grom ABS curb weight 234 lbs). The Grom has a low 30 inch seat height making it very manageable; its size also ensures that motor home owners are sure to find it easy to load/unload, transport and use.

Another aim for the Grom was to provide ‘beyond class’ suspension quality. The 31mm inverted forks – a first for Honda on a 125cc motorcycle – reduces unsprung weight and thanks to the pistons’ greater pressure-bearing area (compared to a standard telescopic fork) offers improved damping feel throughout the stroke. The top and bottom yokes are full-sized, further enhancing handling and rider feel while a lightweight and robust single rear shock operates a simple and tough H-shape, 50mm x 25mm steel box section swingarm.

Fundamental to the Grom’s form and function are its 12-inch cast aluminum wheels, which feature wide 2.5-inch rims. New ‘Y’ shaped spokes not only look great they also save weight and the front 120/70-12 and 130/70-12 rear tires also inject a different dynamic, both in terms of looks and performance. Hydraulic dual piston front and single piston rear brake calipers work front 220mm and rear 190mm discs.

Easy to read for its compact size the LCD digital dash delivers all the information the rider needs – speedometer, twin trip meters, fuel gauge and clock. Resetting the trip meters and clock, or alternation between odometer and trip meter is via switches either side of the display.

3.2 Engine

The Grom’s 125cc two-valve air-cooled engine is based on one of Honda’s most well-proven power units; known for its fuel efficiency, ease of use and longevity. Further development of the engine for the Grom has resulted in improved fuel economy; the engine uses low-friction technology such as an offset cylinder and a roller-rocker arm for the valve gear. Reducing crank inertia has also resulted in improved throttle feel and a smooth power delivery.

Imparting a motorcycle feel to the Grom, the four-speed gearbox is managed via manual clutch and offers smooth and consistent gear changes. The 15T gearbox sprocket, 34T final drive sprocket and 12-inch wheels deliver lively around-town response plus the ability to travel slowly in a high gear – perfect for threading easily through tight traffic.

Sophisticated PGM-FI guarantees highly efficient combustion, and works in conjunction with both air intake and exhaust to deliver an involving experience at the throttle. The air intake connecting tube and funnel is divided in two, allowing its length to be optimized for consistent torque delivery at low and mid rpm. A large, 3-liter airbox and panel-type, wet paper filter provide reliable and quiet airflow; the filter itself has a life of 10,000 miles.

All in all the Grom’s engine packs a perfect blend of punchy roll-on performance with useful, accessible and fun all-round ability. The effort put into reducing internal friction and increasing intake and exhaust efficiency has also produced a highly economical unit.
