1999 Aprilia RS250 Challenge Cup



Additional photos are available here for your perusal.

In 1994, Aprilia released the RS250, a road-legal replica version of their RSV250. Powering the RS was a modified version of the liquid-cooled, 249cc, two-stroke, 90-degree V-Twin from Suzuki’s RGV250. The RS’s engine utilized the Suzuki’s 34mm Mikuni flat slide carbs, though it featured its own Aprilia-designed expansion chambers, barrels, air-box, and exhaust system, a revised ignition and ECU, and a higher compression ratio. Building on the already well-designed single-crank V-Twin developed by Suzuki, the changes made in Noale afforded the RS more mid-range power. What really made the RS250 special, however, was its chassis design. Derived from the bikes built by Aprilia’s factory race program, the RS250 used a polished alloy twin-spar frame paired with an adjustable magnesium alloy banana swing-arm. The trick alloy frame was fitted with 41mm inverted Marzocchi forks and a Sachs monoshock in the back — both adjustable for preload and rebound damping.

The RS250 remained in production, receiving various updates and tweaks – including a significant revamp in ’98 — before Aprilia pulled the plug on the 250 in 2004. Despite a decade-and-a-half having passed since the last RS left the factory, the track-oriented V-Twins are regarded incredibly highly today. MCN has gone as far as to call the RS250, “Simply one of the very best, least-compromised sports motorcycles money can buy”, and VisorDown more recently stated, “The real problem with the RS250 is that if you want one, a good one, you’re too late.”

This example is VIN: ZD4LDA500XS0181. The seller purchased the bike from a private party seven years ago.

During his ownership, the seller has covered approximately 500 miles. The odometer shows 3,144 kilometers (1,953 miles). He notes that the bike only has “200 miles on it since the top end rebuild.”

The seller has included some photos showing the bike in action!

We’ll refer to the seller for a more in-depth description of this example’s service history:
The bike was overhauled in 2020 which comprised of a full top end rebuild including re-plating the cylinders and the addition of the tuning parts. Full re-paint (no fairing repairs needed), chassis inspection and clean / lubrication was also performed. There were some cracks in the engine cradle which is common on this bike. It was professionally welded and has not presented any new issues since. The brakes were stripped, cleaned and the new lines added. Many fasteners were replaced with stainless steel to avoid future corrosion. Always run on VP Ethanol free fuel to avoid gas tank swelling.
