“I brought the 2021 model used with 300 miles on it .. Had it for 3 months now put 500 miles on it .no problems what so ever. changed the rear sprocket from 52 teeth to 48. Seems like the sweet spot for this bike. Adjusted the suspension to my liking. Rides like a dream now. Power is great climbs any hill you throw at it . Took a top speed run with it once. Did a 100 mph easy still had more Only one thing I don’t like is the seat a little hard after about 20 miles. The display is great tach,gear indicator gas gauge,speed in mph. Will be buying a fse 250e for my play bike,to save the 450r for light trails and street,because I like this bike so much. I was a actually thing about buying a kawasaki klx 300 for more money than this,until I test drove one and it sucked. The kawasaki had half the horsepower and was way to far restricted. It would cost you thousands of dollars to upgrade to even start to compare to this bike,and not to mention it weights 304 lbs for a 300.”

Man where do I start!! I was on the fence about one of these bikes for a while. I’ve owned a lot of Japanese dirt bikes and multiple DRZ400’s for dual sporting.
I’ve now owned my GPX FSE450R for almost two years and literally couldn’t picture owning anything else. It fit that perfect gap for me that all the large manufacturers are ignoring.
This thing feels great in the trails, the suspension out of the box soaks up the rough gnarly stuff like a dream. It’s not overwhelming heavy and feels light on its feet for what it is. These 450 zongshen motors have a fantastic broad torque curve that isn’t overwhelming but still powerful. All I’ve changed was the addition of some Tusk Dsport DOT tires and I use my bike to ride 120 miles round trip to work occasionally.
Stop overthinking it and order one!
