If you are weighing a Honda Grom vs Navi, size and price usually come first. The Honda Grom is a 125cc single-cylinder bike aimed at new riders and at anyone who wants cheap, fun riding. This guide does not cover the Honda Navi’s specs, so the comparisons below use the Grom and two 125cc rivals, the Kawasaki Z125 Pro and the Kymco K-Pipe 125.

The table shows the core numbers side by side. Use it as a starting point, then read the sections below for what each number means on the road.

Honda Grom vs Navi Engine and Performance

The Grom uses an air-cooled single-cylinder four-speed engine with two valves and a single overhead cam. The 2014 model had a 4-speed manual transmission with chain final drive. That setup is typical of the 125cc class, which is aimed at new riders as learner bikes.

On the MotoGP Werks dyno, the Grom made 8.3 hp and 7.6 lb-ft of torque. Its power peak comes at 6,400 rpm. For you, that means the Grom delivers its best power at lower revs than the Z125 Pro.

The Z125 Pro makes 8.0 hp at 7,700 rpm and 6.4 lb-ft of torque. To get its peak, you need to rev it higher. Riders who like to work the engine through the rev range will notice that difference.

Fuel injection is standard on the Grom family. The 2014 model used it rather than a carburetor, and the 2026 Base, ABS and SP all use fuel injection too.

Honda Grom vs Navi Weight and Ergonomics

The 2014 Grom has a listed wet weight of 225 lbs (102.1 kg). Weight depends on the version. One listing gives the Grom ABS 231 lbs and the standard Grom 227 lbs, both with fluids and a full tank.

Another listing gives the Grom ABS 227 lbs with standard equipment, required fluids and a full tank. The figures differ by only a few pounds between listings. Either way, reviewers describe the Grom as light and agile, qualities that build rider confidence quickly.

Handling is neutral and precise, and the Grom is the easiest of the group to maneuver at low speeds. That matters most in parking lots, U-turns and slow traffic. The stepped seat, however, could feel tight for taller riders.

Seat height on the 2014 Grom is 29.7 in (754.4 mm). Check that number against your own inseam before you buy. The ABS version has 7 in (177.8 mm) of ground clearance.

The front suspension uses a 31 mm inverted fork, with 3.9 in (99.1 mm) of travel on the 2026 ABS. Another listing gives 4.3 in of front travel, so confirm the figure for the model year you are considering. At the rear, a single shock with a box-section steel swingarm gives 4.1 in of travel.

Braking is simple on the ABS version. It uses a single 220 mm front disc with a 2-piston hydraulic caliper. The ABS system helps keep the front wheel from locking and keeps the rear wheel down during hard braking. The SP has the same front brake without ABS.

The rear uses a single 1-piston caliper on a 190 mm disc.

Honda Grom vs Navi Features

The LCD digital dash shows the speedometer, odometer, A and B trip meters, clock and fuel gauge. Another listing adds a gear-position indicator and tachometer alongside those readouts. For daily riding, a gear indicator helps you keep track of shifts without looking down.

The Grom uses a stacked LED headlight. The 2014 model had a multi-reflector headlight and a bright LED taillight. Both setups keep the front and rear lighting simple and easy to service.

The wheels are 12-inch cast five-spoke units. The frame is a compact steel mono-backbone. Those choices keep weight low and give the bike its small footprint.

Fuel capacity has changed over the years. The 2014 tank held 1.45 gal (5.5 L), while the 2025 Base lists 1.6 gal (6.1 L). Ride range depends on how you ride, so check the current spec sheet before a long trip.

The 2025 Grom has a 220 mm front disc with a dual-piston caliper, and ABS is available on the front only. The same year’s single rear shock offers 4.1 in of travel with no adjustment. If you plan to tune suspension, that lack of adjustment is worth knowing.

Honda Grom vs Navi Price

The 2014 Grom was priced at $2,999. The Kawasaki Z125 Pro is listed at $2,999, and the Kymco K-Pipe 125 at $1,999. On price alone, the K-Pipe is the lowest of the three.

Reviewers found the K-Pipe’s brakes soft and spongy. A lower price does not offset brakes that feel unreliable, so test them before you buy. A test ride tells you more than a spec sheet does.

Current Grom pricing depends on model year and version, including whether you choose the ABS or the SP. For those numbers, read How Much Does the Honda Grom Cost? 2025 Prices. Use the 2014 figure above as a historical reference only.

Which to Choose and Who Should Skip Each

The 125cc class is aimed at new riders as learner bikes and as cheap playbikes for experienced riders. The Grom targets youthful riders new to the sport, and it also appeals to enthusiasts who want an inexpensive way to ride. If you are new and of average build, the Grom’s light weight and easy low-speed handling are strong points.

Skip the Grom if you are a taller rider who finds the stepped seat tight. Test the seat before you commit. If you plan to own it for years, read the Honda Grom Maintenance Intervals: Service Schedule Guide so you know the service schedule up front.

Choose the Z125 Pro if agility matters most. It was the most agile bike in the group, and it has the highest and most rearset footpegs. Check that footpeg position against your legs and back before you buy.

Choose the K-Pipe if stability in bends matters more than agility. It felt more stable in bends than the others, with a more commanding view of the road, but it was less agile. Skip it if you want quick direction changes, and test the brakes before you commit.
