Inspiration, design, performance. The Nami RS, a new kind of electric scooter, has aroused great interest and a lot of curiosity. The official premiere to the public took place on May 22, 2021 during the PIT BIKE race in Toruń. Under its white coat, this prototype is based on the Burn-E model with increased technical specifications, for use on the track. Focus on its design with Marek Tokarewicz, exclusive distributor of Nami Electric in Central Europe and manager of the Polish company Zwinnemiasto.
Who is behind the project?
It is about one person: Krzysztof Michalski - Polish engineer working for us. This is the sixth electric scooter built by Krzysztof. We call him the “Leonardo da Vinci” of electric mobility. He made two prototypes entirely from scratch as part of his university engineering project. He also made some great tweaks for well known brands like polished Dualtron Spider, Golden Dualtron Thunder and more adventurous version Wolf Warrior.
For the Nami RS, Krzysztof was inspired by the organizers of the ESC (Electric Scooter Championship). The goal was to create a racing scooter. That's why this project is so different from basic customization work. Let's be honest: there is nothing in the NAMI RS that can be called “ordinary” or “common”! This is the only example of its kind, and the interest and enthusiasm it has generated among the riding community is completely understandable.
How is the NAMI RS different from the Nami Burn-E?
The NAMI RS racing scooter is designed to ride on kart tracks that have many turns. The basis for this extensive modification - which took a total of 170 hours - was the Nami Burn-E 72V 32Ah version. One of the goals set by the creator was to reduce the weight of the scooter. And we did! NAMI RS weighs 44.8 kg. This was made possible, among other things, by choosing the lightest possible pneumatic shock absorbers. The weight of the entire structure has also been reduced by a much thinner frame. You don't need a keen eye to see special fiberglass fairings on it that improve the aerodynamics of the ride. The other modification takes place on the handlebar which has been shortened. Fast, sporty driving with lots of corners requires a different driving position than conventional city or off-road driving. After appropriate calculations, the design of the NAMI RS was precisely adapted to the racing conditions. The geometry of the vehicle is also influenced by the lowered suspension, which makes the scooter much more stable even at the highest speeds.
What were the other technical specifications that have been thought of for a racing electric scooter?
To make the NAMI RS easier to control, we opted for a central oil-filled steering damper. Unlike the stock one, it is attached to the front of the swing arm base and steerer tube. Thanks to this, it does not protrude on any side. Additionally, it has smoother characteristics and a larger turning radius. To have the best grip on the track, we opted for PMT slick tires. The use of a narrower front tire and a wider rear tire provides geometry similarities comparable to racing bikes. The author was inspired by the solutions used in high-end Moto GPs. Thus, the NAMI RS scooter allows you to turn on the basis of anti-torsion, and it is easier for the driver to maintain balance during dynamic driving.
NAMI RS is equipped with engine cooling fans which lower their temperature. Interestingly, they are more efficient than the heaters used in higher end models of electric scooters such as Rion or Weped. There, the openings in the engine side covers give off heat by convection. The scooter uses a radial fan that mechanically draws air from inside the motor to the outside, thereby cooling the motors.
The Nami RS is equipped with Magura MT5e brakes with different disc diameters. There is a 160mm disc up front and a 140mm disc out back. Why such sizes? Everything has been carefully calculated. Larger discs would be an obstacle when tilting during cornering, which cannot be avoided when driving on the circuit! It has the same front brake cooling system as the Moto GPs. Inspiration should always come from the best. There were also some minor changes. For example, grips and handlebar ends have been replaced, the display box has been added, the throttle lever and its location have changed - so that handling the throttle while racing is even more convenient and precise.
Where did the idea for the Martini Racing colors come from?
The creator of the scooter loves old sports cars. The paintwork used on the NAMI RS is its way of paying homage to racing classics. The NAMI RS is like a classic Porsche 911 RSR among electric scooters. In the 1970s, the aforementioned Porsche model was represented by the colors of Martini Racing.
What improvements could still be made to this version 1 of the NAMI RS?
Krzysztof of course has many ideas on what could be improved in future versions. Additional modifications could include, for example, carbon brake discs, a carbon front fender, an additional fairing on the steering wheel (a another reference to ESC racing). The EXA shocks used in the prototype would eventually be replaced with DNM air shocks. There was even an idea to build a hinged platform cover - allowing quick "plug and play" battery replacement - on the tire changing process on an F1 car! The capacity of the battery could then be suitably matched to the length of the racecourse. Using smaller batteries on shorter tracks would reduce the weight of the scooter, resulting in faster laps. These are of course not the only modifications envisaged. At this point, we don't want to reveal them all. The first version of NAMI RS is based on the same controllers and motors as the basic version of Nami Burn-E (8400W). For future versions, an additional "power" kit (optional) can be provided, which can increase the power of the racing electric scooter to 15,000W and allow the NAMI RS to exceed the speed of 130 km/h!
Will the NAMI RS one day be marketed?
So far, interest in the NAMI RS scooter has not waned. Many customers are ready to get it. Among the many enthusiasts delighted with the performance of the NAMI RS was Kilian Larher - Nami Electric sponsored ESC racing driver. Interestingly, there is a good chance that this is not the "only" NAMI RS created by Krzysztof Michalski. While such a model is unlikely to go into mass production, creating a few more RS copies as part of the limited edition seems within reach. Making the first version is always the hardest and longest step. Now, this first version can be used as a solid starting point for subsequent units. The author himself expresses great interest in continuing the project. That's why we hope that in the near future we can introduce you to more parts of the NAMI RS Race Edition!
