ZX7R -1 Sprocket
It fit great and it was cheap. Huge gains in acceleration. Can’t really comment on durability, only have about 500 on it but its steel and should last.

looks like OE
Bolted straight on. Great price. Durability unrated too soon to tell.

Helped wake up the 06' F4i
JT Sprockets came recommended to me. I purchased it and went one down on the front. It woke the bike up in the mid range and off the line. It threw the speedo off 10% exactly; so 66 mph on the dash is 60 mph, 88 on the dash is 80, and so on. It fit well, too early to tell how long it'll last. It also helps the bike wheelie a little easier too. This should have been the stock gearing, it puts the engines power more where you need it. Now I just need a speedo healer. The Superstore got it here right when they said they would.

JT 525 15tooth sprocket
Good quality hardened steel, recommend changing this on every bike going down 1 tooth makes a nice difference on the bike. My speedometer is off by about 5mph on my CBR F4. But this is what the bike should have been running out of the factory.... if you want even more pickup order a larger rear sprocket to complete the transformation

JT-25 Front Countershaft Sprocket
Was a little apprehensive about installing the front sprocket at first, but it was incredibly easy. My CBR 600 F4 has low-end torque that is crazy now, but I am going to need a "Speedo Healer" to get my speedometer correct again (about 10 mph off). Very economical way to tap in to your motors potential. I would recommend to anyone wanting to better their "holeshot".
