Thought I would post some figures for people to look into if they are thinking of the 19t sprocket. I have recently fitted one and think that it has made a fantastic difference. For instance if you gun it in 2nd it will fly up to 55mph(not redlining it) 3rd up to 75mph and so on. But the best bit is cruising. At 60mph it is only doing 3K revs and at 80mph 4K.Looking forward to getting it on the motorway to see what it does at 90mph. Its like you have another gear that I was always looking for before I fitted it.Old one was a 17t. Best thing I ever did to my bike..I love it.
Anyone else feel the same way or is it just me?
