Super ræs til fattig pris
Ved direkte sammenligning af Max Biaggi’s dedikerede superbike racer og den nye Aprilia RSV4R, er slægtskabet umiskendeligt trods de enorme forskelle.
Aprilia’s race og produktionsafdeling har arbejdet tæt sammen, og gennem hele udviklingsforløbet vurderet samtlige aspekter for bedst muligt at tilgodese begge markeder.
V4 motorkonfigurationen blev valgt med det specifikke formål at vinde løb på banen, og alle tekniske beregninger og beslutninger er truffet i Aprilia’s race afdeling. Dette har resulteret i at løsninger som anvendes i racesammenhæng også findes på gadeversionen RSV4R.
”Ride by wire”, slipperkobling mv. er ikke et ukendt begreb på sportsligt orienterede motorcykler, og er nu normen på Aprilia’s topmodeller.
MagaCin har kørt RSV4 Factory verdenspremieren og ved kåringen af årets mc, og kan stå inde for at det er lykkedes producenten til fulde at implementere de sportslige elementer.
Den mere økonomisk overkommelige RSV4 slap som tidligere nævnt mindre heldigt gennem den nylige presselancering, som blev aflyst på grund af en række motorhaverier.
Ingen tvivl om at problemerne er løst når RSV4 R rammer det danske marked, efter den sidste hurdle med at finde en dansk importør til 2010 er overstået.
