The grain of a hand-stitched leather seat. The brushed finish of an aluminium mudguard catching the light. The clean line of fork gaiters fitted to the millimetre. You’ve chosen every piece to give your machine a character that’s unmistakably yours — and now a question keeps coming back: will it pass inspection?
Whether you’re facing an MOT in the UK, a TÜV in Germany, a CT in France or any periodic inspection across Europe, the fundamental distinction between cosmetic parts and functional parts applies everywhere. This guide breaks it down — by part type, then country by country.
This article is for informational purposes only. It does not replace the regulations applicable in your country or the specific terms of your insurance policy.
Three Categories of Parts
1. Purely cosmetic parts — no type approval required
Seats, fork gaiters, mudguards, side covers, engine guards, grips: these parts don’t affect any safety system. No vehicle inspection anywhere checks them.
2. Functional parts — compliance required
Lighting, exhaust, braking, tyres, steering and suspension are inspected at MOT, TÜV or CT.
3. The grey zone
Handlebars — part of the steering system (an inspection point). A replacement that preserves original dimensions won’t cause issues. The TÜV in Germany is strict if riding height changes significantly.
Levers — interact with braking. Replacement levers maintaining the same travel are compliant.
Mirrors — presence checked (at least 1 in UK/FR, 2 in DE). Design is free.
Headlamp grilles — no issue in practice with open classic-style grilles.
The principle: it’s not the part that creates an issue, it’s the effect of its installation on an inspected safety component.
BAAK Exhausts: Euro 4, Designed for the Road
BAAK designs and manufactures its own exhaust systems in our workshop in Rillieux-la-Pape, near Lyon. Euro 4 compatible, covering Triumph Bonneville, Royal Enfield 650, Moto Guzzi V7. Our silencers stay within manufacturer noise values. Customer feedback consistently confirms they pass inspection. We recommend keeping the original exhaust as a fallback.
E-mark: Non-Negotiable on Lighting
At BAAK, every LED indicator, position light and headlamp unit carries E-mark approval — recognised across Europe and the UK post-Brexit.
Country by Country
UK MOT: annual, 3+ years. E-mark recognised post-Brexit. BAAK lighting and exhausts pass without issue.
Germany TÜV: strictest in Europe. ABE/ECE certificate often required for exhausts. Keep documentation with vehicle papers.
France CT: 78 points. Noise measured vs registration card. 2020-2021 bikes due by end of 2026.
Europe: Directive 2014/45/EU. Same cosmetic/functional principle everywhere.
Three Questions Before Buying
1. Does this part affect an inspected element? Lighting → demand E-mark. Exhaust → verify Euro compliance. Handlebar → preserve geometry. Seat, gaiter, mudguard → no approval needed.
2. What’s the traceability? An inspection won’t check your leather, but daily use will.
3. Does the installation preserve inspected elements?
Insurance
Cosmetic modifications generally don’t require a declaration. For functional parts, check your policy terms.
Every part that leaves the BAAK workshop in Rillieux-la-Pape is designed to elevate your motorcycle while respecting the demands of the road. E-marked lighting. Euro 4 exhausts. Handlebars preserving steering geometry. Cosmetic parts untouched by any inspection. The rest — the grain of the leather, the curve of a mudguard, the deep note of a BAAK silencer — that’s what separates a modified motorcycle from a BAAK motorcycle.
