I doubt you'll notice a difference. I did one up in the rear on my gsxr, and I couldn't feel the difference. I know it helped, but not really any seat of the pants.I am debating on going fomn a 49 to a 50. Already went down 1 on the front. Just not getting the torques i want. Just dont want to buy the 50 and realize I should have gone with tha 51. I think 52 is overkill for my needs.
