Today I took a ride of n250 the engine was smooth but the front suspension was going up and down, like a vibration not wobbling but vibration up and down. It seems too soft. I was at 60kmph only. I asked a guy who has the bike and he said he also experienced this. Do you guys know what it is??? If this is a thing with the bike I'll drop the purchase and look else where
