Shark25 Motor

The Shark25, NSR's short-can motor that bites the track from the first lap

NSR has been an unavoidable reference in the world of competitive slot racing for years, and its motor catalogue is one of the reasons for that prestige. The Shark25 Motor (NSR3003) is a short-can motor designed to offer a well-balanced ratio between RPM and torque: 25,000 rpm and 176 g-cm at 12V. These two figures translate on the track into a vigorous and progressive response that the most demanding enthusiasts appreciate.

Main features

• Nominal speed: 25,000 rpm at 12V
• Torque: 176 g-cm at 12V
• Format: short-can
• Brand: NSR (reference NSR3003)

The short-can format is one of the most widespread in modern competitive slot racing. It allows integration into a wide variety of chassis with sidewinder (motor parallel to the rear axle) or anglewinder (motor angled relative to the rear axle) configurations, depending on the chassis design you use. It is advisable to check your chassis specifications before mounting the motor to confirm the correct arrangement.

Behaviour and performance

With 25,000 rpm, the Shark25 sits in a mid-high performance range, suitable for club categories where the regulations set a ceiling on revolutions and prioritize control over top speed. The torque of 176 g-cm provides strong acceleration from low speeds, which favours corner exits and reduces the pilot's margin of error during late braking.

NSR is known for the consistency of its motors: tight tolerances, long-lasting braids, and stable operation over extended sessions. The Shark25 maintains that quality construction line that has made the Italian brand synonymous with reliability in the paddock.

Recommended applications

This motor fits particularly well in:

• Competition chassis in 1/32 scale with sidewinder or anglewinder configuration.
• Club categories with a revolution limit around 25,000 rpm.
• Setups aimed at a balanced driving profile, with good torque in corners and competitive top speed.
• Drivers looking for a smooth running motor and predictable behaviour during long sessions.

Usage recommendations

As with any competition motor, we recommend a progressive break-in period before demanding maximum performance. Adjust the braid pressure, check the pinion clearance during assembly, and ensure that the drivetrain alignment is correct to avoid premature wear. NSR has a wide catalogue of spare parts, making long-term maintenance of the motor and transmission assembly easier.

Frequently asked questions

Is the Shark25 suitable for club categories with motor limits?

It depends on the regulations of each championship. Its 25,000 rpm places it in a very common range for mid-high level club categories. Always check your league's rules before purchasing.

What type of motor configuration does this motor support?

As a short-can motor, it is compatible with sidewinder (motor parallel to the rear axle) and anglewinder (motor angled relative to the rear axle) configurations, depending on the chassis. Confirm compatibility with the specifications of your specific chassis.

Does it require a break-in period?

Yes. Like any slot racing motor, the Shark25 benefits from a progressive break-in at reduced voltage before operating at full performance. This helps to settle the braids and improve the motor's efficiency from the start.

What pinion should I use with the Shark25?

NSR offers a wide catalogue of pinions compatible with its short-can motors. The choice of pinion will depend on the crown gear you mount and the gear ratio you seek for your track. Consult your chassis technical sheet or contact us if you have any doubts.

Is it compatible with chassis from other brands?

The short-can format is standard in the industry, so it is compatible with many chassis on the market. However, it is always advisable to verify the motor housing dimensions in your chassis before proceeding with the installation.

The NSR Shark25 motor (NSR3003) is a short-can slot car motor delivering 25,000 rpm and 176 g-cm of torque at 12V. Designed for competitive 1/32 slot racing, it suits sidewinder and anglewinder chassis configurations, offering consistent performance across long club sessions. A reliable choice for intermediate to advanced slot racers looking for a balanced power-to-torque ratio.
