APRILIA RS250 SP Racing Bike / Aprilia CUP Bike RS 250

OHVALE / Aprilia RS250 SP & RS 250 SP2

The Aprilia production racer RS250 SP was developed by Aprilia Racing in close collaboration with Ohvale and the Italian Motorcycling Federation (F.M.I) as a logical progression to nurture young talent. For the riders who have already raced on the OHVALE GP-0 / OHVALE GP2 and now want to reach the next higher level, but also for young people who want to get into motorcycle motorsport. Low weight, excellent chassis, TOP equipment are the ideal prerequisites.

This formula is part of the Italian Aprilia Sport Championship, which is an integral part of the Italian CIV JUNIOR program. The racing calendar includes several races for young drivers aged 11 and over.

The Aprilia RS 250 SP, based on the Aprilia RS125 road model, utilizes all the know-how and technology of the Noale Racing department and is equipped with the best racing components. A water-cooled 250 ccm 4-valve engine with just under 30 hp (SP1) or just under 36 hp (SP2) is used. The use of fine CNC parts helps optimize the bike for track use while saving weight.

Due to its low weight, the vehicle is ideal for young drivers from around 11 years of age (approx. 145 cm), also for beginners.

Brembo monoblock saddle, OHLINS suspension, Marchesini rims, Pirelli Diablo slicks, SC Projekt exhaust system and Alfano 6 display are just a few components of the fine equipment list.
