Motorcycle News - Super Scooter: A NOS-fuelled Piaggio NRG drag racer
https://ift.tt/2Zx4QJo
This plucky little sprinter started out as a Piaggio NRG—a 50 cc scooter from the mid-2000s—but it’s come a long way. Power is up from the stock 4 PS to a heady 20 PS, and the curb weight is just 56 kilos—124 pounds.
“On eBay I was selling a Honda NS400R fairing and exhaust,” Nick explains. “I was contacted by Mirko Toth, through a mutual friend of Jens at JvB Moto here in Cologne.”
Mirko had been working at Scooter Centre in Cologne for years, and had a lot of experience building scooter drag racing motors. He’d just bought the Piaggio; it had already been ‘converted’ for drag racing, with a makeshift hardtail setup that consisted of a steel table leg where the rear shock once was.
But first, the guys had to drastically rework the scooter’s frame. Not only did the table leg get tossed, but also the original engine brackets—so the entire back half of the frame is new.
For the forks, they installed a set of Aprilia units, shortened them to just 80 mm of travel, and shaved off their brake mounts. The handlebars are ape hangers from a Honda V30 Magna—shortened, narrowed and mounted upside down on a mountain bike stem.
With the rolling chassis sorted, Nick set about adapting his tank and tail to fit the NRG. The tank was originally adapted from a Kawasaki AR50, but the tail unit is a complete custom job. Nick made it from carbon fiber, and bolted it to an aluminum seat pan.
As Nick started buttoning up the last bits of the chassis and shell, Mirko turned his attention to the motor. He went to town, starting with a Polini Evolution 70 cc kit with longer con-rods and a stage six crankshaft.
The block, cylinder, intake, exhaust and piston were all ported and flowed, to bring the original NRG motor up to 20 PS. And the clutch is set up so that it’ll launch from 6,000 rpm, with power peaking at 9,300 rpm.
“Unfortunately this also meant the we needed to get the bottle filled here in Germany, as you cannot ship a full NOS bottle (not really a surprise).”
Mirko’s actually still tuning the NOS setup, but the guys are expecting eight to 10 more PS when it’s ready. And then it’ll be time to go racing.
Nick called in help for one detail; tattoo artist and pin-striper, Von Maze laid down a pin stripe and a stunning pair of tank graphics, all by hand. The logos read ‘ANX Prototypes’—the name of the bike building business Nick is launching. If this boosted two-stroke doesn’t look like the most fun thing on two wheels, maybe check your pulse. And if you’re in Europe, look out for it on the sprint scene—and let us know how it sounds!
