BMW C 400 GT: specifications, pros and cons, compatible accessories
BMW’s scooter, with a catalog that resembles a motorcycle’s
Large wheels, a comfortable seat, and spacious under-seat storage. The C 400 GT is used every day in the city and on extra-urban routes, which is precisely why it needs two things scooters rarely have: a sturdy kickstand plate and side protection.
- In summaryFor everyday use: protection against a stationary fall matters most of all.
- Do this right awayKickstand plate, crash bars, tunnel bag.
- For the top caseA top-case mounting plate is required, and it varies by model year.
- AttentionThe crash bars are for the 2025-on version.

Who it’s recommended for
It’s the right vehicle if
- You use it every day in the city and on extra-urban routes
- You need more comfort and wind protection than a typical scooter offers
- You want under-seat storage that fits two full-face helmets
- You’re shorter: the seat is 775 mm high
- You’re interested in the stability of the 15-inch wheel on cobblestones
Look elsewhere if
- You do a lot of motorway riding: 34 hp leaves little margin for overtaking
- You’re looking for a lightweight vehicle to move by hand: it weighs 212 kg
- You need best-in-class fuel economy
- You want an accessories catalog as extensive as a motorcycle’s
- You park in very tight spaces
In short: it’s the right scooter for anyone who covers serious mileage every day and wants motorcycle-level fit and finish and comfort. If you’re looking for the same kind of use with a lighter, more agile vehicle, take a look at lower-capacity high-wheel scooters; if you do a lot of extra-urban riding, a motorcycle like the G 310 GS costs less to run and performs better outside the city.

What to fit, in order of priority
On a vehicle for everyday use, damage comes from parking, not speed.
- 1
CNC aluminium side-stand platePart number CJC092, compatible with the C 400 X and C 400 GT from 2018. With 212 kg on hot asphalt or gravel, the stand sinks in. - 2
Crash bars with footrests includedPart number CHG102 for the version from 2025: 22 mm Q345B steel, protects the bodywork and provides additional support for the legs. - 3
Top case plateThis is the part you need before the top case: without the plate, the top case cannot be attached. This one is for the C 400 GT from 2024; for earlier model years, there is the C 400 X and C 400 GT from 2018 version. - 4
Aluminium top caseFor those who use their scooter for work: extra capacity beyond the under-seat compartment. Must be paired with the plate for your model year. - 5
15-litre tunnel bagDesigned for scooters: with rain cover, shoulder strap, and MOLLE system. It makes use of the space in front of the seat, which would otherwise remain unused. - 6
Kaoko mechanical cruise controlLocks the throttle without electronics. On long extra-urban trips, it is the simplest remedy for a wrist that gets sore. Part number for the 2019-2021 C 400 X and C 400 GT from 2019. - 7
Folding mirrorsThey fold away to pass between cars in a queue without breaking at the first contact. With the adapters, any model can be fitted to the original thread. - 8
Waterproof motorcycle coverOn scooters parked on the street all day, the seat and instrumentation are damaged by the sun.

Frequently asked questions
Is a side-stand plate really useful on a scooter?
In this case, yes. At 212 kg, the original side stand sinks into hot summer asphalt and gravel. It is the accessory that prevents the most damage on a vehicle parked on the street every day.
What is needed to fit a top case?
Two parts: the top case plate and the top case. The plate varies by model year - there is one version for the C 400 X and C 400 GT from 2018, and another for the C 400 GT from 2024 - so it is the first code to check, even before choosing the top case.
Does the crash bar fit all C 400 GT models?
No, code CHG102 is for the version from 2025 onward. On earlier series, the mounting points are different: check the year before ordering.
Do the C 400 X accessories fit?
Many do: the side-stand plate, top case plate from 2018, cruise control and tunnel bag use the same codes. The two versions share the chassis and main mounting points, but not the body panels.
Do you need a top case if there is already under-seat storage?
It depends on how you use it. The storage compartment holds two helmets, but if the scooter is used for work or deliveries, the top case adds capacity without taking up helmet space.
Can it be used on the motorway?
Yes, but with limited margin: 34 hp is enough to maintain the pace, not for quick overtaking uphill. On mixed urban and rural roads, however, it is in its element, and that is where the cruise control makes a difference.
