SideWinder motor mount

The NSR SideWinder motor mount that makes a difference in your setup

The reference NSR1274 is the extra light SideWinder motor mount in yellow, designed for the NSR Classic and Abarth 500 chassis. A small but highly important component: its rigidity, alignment, and weight significantly affect the response of the rear end and the efficiency of power transmission.

Function and performance

The motor mount is the piece that anchors the motor to the chassis and determines its position relative to the rear axle. In a Sidewinder configuration —where the motor is positioned parallel to the rear axle— the correct fixation of the mount is crucial to ensure precise engagement between the motor pinion and the crown gear, avoid vibrations, and maintain the proper tension throughout the race.

The extra light version from NSR sacrifices grams without compromising structural integrity, allowing for more precise weight distribution of the car. The yellow colour is not just aesthetic: it facilitates quick identification in the pit when working with multiple sets of spare parts.

Compatibility

• NSR Classic chassis
• NSR Abarth 500 chassis
• Sidewinder motor configuration

If your setup uses an inline or anglewinder configuration, this mount is not suitable: always check your motor arrangement before placing the order.

Installation and preparation

The installation of this mount does not require special tools, but attention to detail is necessary. It is advisable to verify that the pinion and crown gear are well aligned after installation and that the lateral play of the motor is kept to a minimum to avoid power loss. NSR offers a wide range of complementary spare parts —crown gears, pinions, axles, and tyres— that allow for precise adjustments of the assembly.

Common mistakes

• Confusing the extra light version with the standard version: the weight differs and affects the balance of the car. Ensure you are looking for weight reduction before choosing this version.
• Using the mount on incompatible chassis: although the geometry may seem similar, NSR designs each mount for specific chassis. Respect the indicated compatibilities.
• Over-tightening the fixing screws: this can deform the mount and alter the alignment of the motor, especially in lightweight versions.

Frequently asked questions

What is the difference between the extra light mount and the standard NSR mount?

The extra light version is made from a material or geometry that reduces the total weight of the piece compared to the standard mount. This allows for fine-tuning the mass distribution of the car, especially relevant in club racing where every tenth of a gram counts.

Is this mount compatible with all NSR chassis?

No. The NSR1274 is specifically designed for the NSR Classic and Abarth 500 chassis in a Sidewinder configuration. For other chassis or motor configurations, consult the NSR mount catalogue.

Can I use this mount with any NSR Sidewinder motor?

In principle, yes, as long as the motor is compatible with the Classic or Abarth 500 chassis. However, we recommend checking the specifications of the specific motor you intend to install to ensure a correct fit.

Does the yellow colour have any technical function?

The colour is a visual code that NSR uses to quickly identify the extra light versions within its range of spare parts. It facilitates organisation in the pit, but does not imply any additional technical difference beyond the reduced weight.

How many mounts are included in the pack?

The available information does not specify whether it is a single unit or a pack with multiple pieces. We recommend checking the exact contents in the product sheet or contacting us before placing the order.
