      I took a test ride of Guerilla 450 and felt so good. You can feel the speed of it since I own a RX 135. This bike is certainly a different breed of RE. Best bike in the speed segment

      Best bike in this price range. It has a strong road presence and great performance. The look is premium. It's perfect for both city rides and touring just go for it! The tyres look muscular, and overall, it gives full satisfaction.
