I just purchased a 88 NX250 as my first bike, i want to learn on this bike and later move onto buying something better for the street and keep this as a toy for light offroading, it came with off road nobby tires, what are my options for some really good street tires? Traction being the key, what size? should i buy tires and wheels if so what size? im a big guy 5´10 260lbs
