Precision 7075 Exhaust for PROMOTO-MX

This precision-machined 7075 aluminium exhaust pipe is a dedicated replacement for the PROMOTO-MX 1/4 motorcycle platform. The barrel and mounting faces are machined from 7075 aluminium and receive an anodised finish to improve wear resistance and corrosion protection under routine off-road model use.

The kit is supplied with the exhaust and the mounting fasteners to allow direct replacement on compatible 1/4-scale frames. It is intended for hobbyist maintenance and tuning tasks where exhaust geometry and robust fitment are required. Not for use on full-size vehicles.

Packing includes

  • Exhaust pipe - 1pcs
  • Grade 12.9 black round head screws 3x10 - 2pcs
  • Set screws 3x6 - 1pcs

Original Name / Part No:

LOS261004

Compatible Models

  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06000
  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR PRO CIRCUIT-LOS06002

Engineered for straightforward mounting and long-term wear resistance, this anodised 7075 replacement exhaust supports reliable fitment and chassis compatibility on LOSI PROMOTO-MX 1/4 models.

What machining standard is used?

The barrel and mounting faces are precision-machined from 7075 aluminium to ensure repeatable fit and surface finish for model-scale assemblies.

How does this part aid tuning work?

Stable exhaust geometry and durable mounting reduce variability in backpressure and alignment, making this a useful component when refining power delivery and sound at scale.

Are the supplied fasteners high grade?

The kit includes Grade 12.9 black round head screws 3x10 and a set screw 3x6 sized for direct mounting to the listed frames.

Where should I check fitment?

Verify clearance around frame mounts and nearby bodywork before final torqueing to ensure alignment and avoid interference with chassis components.

What are the material benefits?

7075 aluminium offers a high strength-to-weight ratio at model scale and, with an anodised finish, provides improved surface hardness and corrosion resistance compared with untreated alloys.
