Robem Engineering riders De Keyrel, Toth to compete in Aprilia RS 660 Trofeo season finale Sunday in Italy

Team thanks Piaggio Group Americas for continued support, offers best wishes to its riders in advance of race at Autodromo Vallelunga Piero Taruffi


Oct. 7, 2021

Kaleb De Keyrel piloted an Aprilia RS 660 to the marque’s first MotoAmerica Twins Cup Championship title this year, and — thanks to support from the Piaggio Group Americas — the Minnesotan has been rewarded with an invitation to compete Sunday in the season finale of the Aprilia RS 660 Trofeo series.

The event takes place at the Autodromo Vallelunga Piero Taruffi near Rome, Italy. Also competing in the RS 660 Trofeo finale will be De Keyrel’s Robem Engineering teammate Max Toth.

Accompanying De Keyrel and Toth on the trip is Eric Vallarta, the owner of Robem Engineering technical partner Velocity Calibrations. Vallarta was responsible for chassis and suspension setup for the Robem Engineering Aprilias during the MotoAmerica season and will help the two riders get their Trofeo-spec Aprilia RS 660s dialed in as quickly as possible. De Keyrel’s Aprilia also will feature a special livery for the event.

On-track action gets underway on Thursday, and the event’s lone race is scheduled to start at 12:15 p.m. Central European Time (6:15 a.m. Eastern) on Sunday.

The five-round Aprilia RS 660 Trofeo is organized by BK Corse and is part of the Campionato Italiano Velocitá (CIV) — Italy’s national road racing championship. The first four rounds of the 2021 season took place at three prominent Italian circuits — two rounds at the Misano World Circuit Marco Simoncelli and one round apiece at the Autodromo Internazionale Enzo e Dino Ferrari in Imola and the Autodromo del Mugello.
