I bought a pair of good condition used ones and had them on my CB350. They are race compound so I was concerned with fast wear on the streets. Whoa, best gripping tires I ever used on my Honda, much softer than the Spitfires I had on before. I even took them to the track one day and they held up great. They didn't wear as quickly as I expected, got around 15,000 kms out out them in 3 seasons. Expensive when bought new, lucky mine cost $25 for the pair. I recommend 110 front and 120 rear, that's what I used and they were perfect.
