I put 26x9x12 in front and 26x12x12 bighorn originals on. They are very smooth and hooks up great. They are heavy and noticed a performance drop so i tweaked the cluthing. Now it is perfect.
Those tires are sweet, congrats. If you need to change clutching. Use purple spring and 22gr ( total weight and weight housing combined).
Still rides quiet and controlled until you punch it. Feels like two different bikes.lol
