one day me and my friends were all ouyt riding and we got lined up like we were gonna race. this is when i just started riding so i wasnt very expirienced. we all revved up our bikes and they took off and i accidently popped the clutch and flipped my 250r 3-wheeler at the time it didnt have a grab bar so i destroyed my plastics. i took the thrre wheeler home and frankenstein stitched all the plastics together with zip ties and went out for the rest of the day and had a good time. Another time my friend was riding his yz490 on the road he came flying up the road wheelieing in about 3rd when it only has 4 gears and flipped it right over the back of him. He slid for about 30 feet on the hard asphalt and tore up his whole back. Now he is afraid to wheelie his bike ever since he did that.
