Let’s explore what types of modifications are allowed, how much it costs, and how to avoid getting fined by the BRTA.
✅ Is Bike Modification Legal in Bangladesh?
Bike modification in Bangladesh is legal, but not everything is allowed. The Bangladesh Road Transport Authority (BRTA) only allows modifications that don’t change the bike's core specifications like engine displacement, chassis, or frame.
🔧 What types of bike modifications are allowed in Bangladesh?
You can legally do:
-
Cosmetic changes like stickers, seat covers, handle grips
-
LED lights (non-blinking and not blue/red)
-
Modified exhausts within sound limits
-
Handlebars and mirrors for better style or comfort
But changing engine capacity, chassis cutting, or tampering with engine number is strictly illegal.
🔇 Can I change my bike’s exhaust or silencer legally in BD?
Yes, but the new exhaust must stay within the legal noise limit. Loud or race-style silencers may attract police attention and lead to fines.

Use fully synthetic engine oil, clean your air filter regularly, and ride at a steady speed. This can boost mileage and keep your engine healthy.
