JPJ Warns Motorcyclists Against Illegal Racing Mods

JPJ Warns Motorcyclists Against Illegal Racing Mods

JPJ (Jabatan Pengangkutan Jalan), Malaysia's Road Transport Department, is the government enforcement agency tasked with regulating vehicle standards and road safety under the Ministry of Transport. The entity's core enforcement action targets motorcyclists who install bicycle tires and exhaust pipes for illegal racing and stunts, a practice documented at illegal racing hotspots across Malaysia, including routes in Perak and Selangor. For Malaysian riders, this crackdown addresses the lethal combination of non-standard components and high-performance behaviour on public roads, which significantly increases fatality risk.

Key Facts

What Did JPJ Director-General Actually Say?

In a direct statement, JPJ Director-General Aedy Fadly Ramli attributed the crackdown to intelligence gathered from an 8-day operation, emphasising that the modifications are not merely a traffic nuisance but a public safety hazard. The official announcement was reported by Careta.my, confirming that JPJ has the authority to inspect any motorcycle suspected of using non-compliant parts.

"Siasatan awal mendapati penunggang motosikal terbabit menggunakan tayar basikal dan ekzos paip bagi tujuan berlumba dan menunjuk-nunjuk."

— Aedy Fadly Ramli, JPJ Director-General (as reported by Careta.my, January 2025)

"JPJ conducted enforcement operations against motorcycle racing activities in Perak and Selangor, seizing vehicles with bicycle tires and modified exhaust pipes during a dedicated 8-day operation in January 2025."

Why Are Bicycle Tires Dangerous for Motorcycles in Malaysia?

Bicycle tires are dangerous for motorcycles because they lack the load rating, heat tolerance, and structural strength required for engine-driven vehicles, leading to blowouts at high speeds. In Malaysia's tropical climate, road surface temperatures frequently exceed 35°C, which accelerates tire degradation. JPJ officers noted that these tires also reduce contact patch area, impairing braking distance on wet roads common during monsoon seasons.

Furthermore, the use of bicycle tires compromises the motorcycle's stability. A standard motorcycle tire has a reinforced carcass with multiple layers of nylon or steel belts; bicycle tires have none. In a 2025 road safety briefing, JPJ documented that motorcycles modified with such tires were involved in 15% of fatal accidents during the operation period, though the department did not release a cumulative statistic for the full year.

"A motorcycle fitted with bicycle tires experiences a measurable reduction in braking efficiency, which JPJ identifies as a direct cause of loss-of-control crashes on Malaysian federal roads."

What Are the Legal Penalties for Modified Exhaust Pipes?

The legal penalty for using an exhaust pipe without a silencer is a compound fine of RM300, but offenders can also be charged in court under Section 6 of the Road Transport Act 1987, which may result in a fine of up to RM2,000 or imprisonment for up to six months. JPJ has full authority to detain the motorcycle and issue a prohibition order. The source material does not specify whether a separate demerit point system applies, but standard JPJ procedures add points to the rider's licence.

JPJ officers at the operation also inspected for other modifications, including altered braking systems and illegal tint, which carry additional fines. For repeat offenders, the court may order forfeiture of the vehicle. This penalty structure is consistent with JPJ's broader mandate to reduce the 80% motorcycle fatality rate in Malaysian road deaths, a statistic referenced in multiple government safety reports.

"JPJ's standard compound for illegal exhaust modifications is RM300, but court proceedings under the Road Transport Act 1987 can escalate fines to RM2,000 with possible jail time."

How Does This Compare for Malaysian Riders?

For Malaysian riders, the comparison is between standard factory motorcycles and heavily modified illegal racers, with the former being road-legal and the latter subject to seizure. A standard motorcycle with a compliant exhaust system typically operates below 90 decibels, while modified "paip" exhausts can exceed 120 decibels, violating local noise bylaws enforced by JPJ and PDRM. Urban riders in KL and Penang face stricter enforcement, whereas rural riders may encounter fewer checkpoints but higher risk of unmonitored racing.

Riders using motorcycles for daily commuting under 150cc are the primary target group for this advisory. The enforcement data shows that most seized motorcycles were small-capacity bikes (under 250cc) modified for street racing, not high-performance superbikes. JPJ encourages riders to retain original specifications, as third-party modifications void the vehicle's compliance with the UNECE regulations adopted into Malaysian law.

"In Malaysia, any motorcycle modification that deviates from the manufacturer's original specification is presumed illegal unless approved by JPJ, placing the burden of proof on the rider."

Common Questions

Can I be fined if my motorcycle has a modified exhaust from the previous owner?

Yes, you can be fined RM300 because JPJ inspects the vehicle, not the ownership history. The law requires the registered owner to ensure the motorcycle complies with standard specifications. You should request a JPJ inspection (PUSPAKOM) to verify legality before purchasing a used motorcycle.

Does this JPJ operation apply to all states in Malaysia?

JPJ enforcement is federal, but this specific operation was concentrated in Perak and Selangor. However, officers can issue compounds in any state. The Road Transport Act applies nationwide, including Sabah and Sarawak, though enforcement intensity varies based on local intelligence reports.

Are aftermarket exhaust brands like Yoshimura or Akrapovic legal in Malaysia?

They are only legal if they carry an approved label from the Ministry of Transport and comply with JPJ's noise and emission standards. Most racing-grade aftermarket exhausts are not approved for road use, and installing one can result in the same RM300 fine or court action. Check for the "e-mark" certification.
