Riders Talk: Aprilia Pegaso 650 User Reviews & Honest Feedback
Today, we’re talking with three experienced riders who’ve spent years riding the Aprilia Pegaso 650. They’ll share their thoughts on performance, comfort, reliability, and how this dual-sport machine holds up in the real world.
Today we’re talking with three experienced riders who’ve spent years riding the Aprilia Pegaso 650. They’ll share their thoughts on performance, comfort, reliability, and how this dual-sport machine holds up in the real world.
Jason from the USA has been riding his 2004 model for nearly five years. “I picked it up used and have done over 15,000 miles on it. It’s been more reliable than I expected, especially for the price I paid.” Ahmed from the UK owns a 2001 EFI version. “I bought it in 2018 as a daily commuter that can handle light off-road tracks. It’s not too heavy, and I like how it feels in the city.” Maria from Spain says she mostly uses hers for trail riding. “I’ve had my bike since 2016. I use it on mountain paths near Valencia and some paved roads. It’s easy to manage and very versatile.”
When asked why they chose the Aprilia Pegaso 650 over other dual-sport bikes, Jason says it was the upright seating and the fact that it shares many components with the older BMW F650. “That made parts easier to find and maintenance cheaper,” Ahmed mentions the affordability. “For the features it offers, it’s a great deal compared to Japanese alternatives.” Maria was looking for a lightweight machine with good off-road manners. “It’s not bulky like larger adventure bikes, and I can handle it easily even on tricky trails.”
On performance, all three agree it’s well-balanced. Jason uses his for long rides and says it holds up well on highways. “I’ve done 200+ mile days without problems.” Ahmed prefers a mix of road and trail. “Seventy percent road, thirty percent off-road is the best use. It’s torquey and climbs well if you don’t push it too hard.” Maria says switching to semi-knobby tires improved its off-road handling. “It’s stable and doesn’t feel nervous on loose terrain.”
Mechanical concerns were minimal but worth noting. Jason had to clean the carburetor after letting the bike sit over the winter. Ahmed replaced the voltage regulator due to charging issues. “That’s a known problem in older models.” Maria hasn’t faced serious problems, just standard maintenance. “Oil, filters, and brakes are easy to service. But I did find the seat uncomfortable after longer rides.”
Would they recommend the Aprilia Pegaso 650 to others? All three say yes. Jason appreciates its simplicity and calls it a solid all-rounder. Ahmed believes it’s a great option for riders on a budget, especially those who enjoy working on their bike. Maria praises its light weight and trail capability. “The Aprilia Pegaso 650 may not be famous, but it gets the job done. It’s the kind of bike you grow to love the more you ride it.”
