if you are looking for a 90 cc or larger, I would highly recommend a honda, suzuki or kawasaki...no name brands do not go through the mud holes , their parts are harder to find than name brands and they constantly shut down after getting wet...my 8 yr old rides a 90 cc honda and it never lets him (or us) down..starts right up, goes through the mud and water with no problems...try craigslist...to give you an idea on price, we paid around $500.00 for his...good luck!
