After 22 years of lisenced riding: 10 I can remember
3 times in the hayfield/pasture while driving to the equipment, street tires are terrible in wet grass. Fortunately damp sod didn't even scratch the paint.
3 times on the street, 1 high side (accident avoidance), 2 lowside (wet leaves twice)
2 times in the yard while in motion, wet leaves once, soft sand once.
2 times while moving the bike turned off in neutral. Both times after drinking heavily and trying to move the bike to a more secure area. Hopefully a third time won't be required to recognize the trend with drinking and moving the bike.
Never owned a new bike, and refuse to "try" friends new or nice bikes. I'm an accident waiting to happen.
