Honda CBR600 F4

 Stock is pretty self-explanatory. 
Mild -  This is about where you'll start to notice a difference in performance.  And is a good place to start if you're looking for a little extra acceleration without sacrificing much higher rpm's on the highway. 
Stage I - Ideal for most sport riding enthusiasts- This is generally meant for someone wanting a lot more acceleration and for easier wheelies etc.  This combo will generally let you pull wheelies in one gear higher than you can with stock.  This is also a good starting combination for roadracing and track days.  With this setup the goal is to get the maximum performance out of a bike without sacrificing any top speed.  This is generally how I think most bikes should come from the factory for optimum performance.  It is about a 10% change.  
Stage II - This is a great setup for effortless wheelies or someone wanting to learn more technical stunt riding and also for drag racing.  Depending on the bike and rider weight, you may see a 5-10% decrease in terminal speed with this kit due to the rise in rpm's.  But you will get to your terminal speed MUCH faster.  You can expect 1-2 second faster ET's once you practice getting the power down efficiently.

If you've heard of 'conversion kits' or 'acceleration kits' before- it is for good reason. Most street bikes were, and still are, originally equipped with 530 size chain and sprockets from the factory. This is mainly because it has been the norm for many years and it is cheaper and easier for them to do everything in one size. Recent exceptions are certain newer mid-sized (600-750cc) sport bikes which now come with a new 525 size. And the new Kawasaki race replicas now come with 520 from the factory because of the obvious benefits!

This auction is the real deal. We only use the very best quality performance parts- No haphazard thrown together, old, outdated, second hand stuff here. This auction is for those who want to the best and expect the best out of their machine.  Don't let someone selling other general bike parts lead you to believe they know what they're talking about.

The lighter sprockets and chain will give you less unsprung weight(rotating mass) which will improve the braking and handling of the bike as well as increase your hp output at the rear wheel and your acceleration. When combined with a shorter gear ratio combo it will give you a lot more pulling power for a quicker launch and easier wheelies, if desired. And the most useful benefit that everyone will appreciate is faster roll-ons in every gear, at every speed.

Converting to a 520 kit the average bike will see a 5% increase in horsepower.  So, 5-7 hp is very typical on a 600.  Not a bad hp per dollar ratio there.  Especially since you have to eventually replace these parts anyway.

Upon request I can also provide some handy tips and tricks for swapping the sprockets yourself. 

So, if your friends are beating you off the line, or making wheelies look easy you now have a secret weapon.  It is also a much less expensive way to replace AND upgrade worn out OEM parts.

For all riders, regardless of whether your interested in this auction-  To avoid an accident and/or damage to your motor, or worse, you should regularly maintain and inspect your drive components.  Its often an overlooked and neglected part of a bike.    To check the condition of your chain, first adjust the tension properly.  With the bike held straight up and down you should have about 3 times the height of the chain top to bottom, measured below the swingarm.  (This is particularly important if you are doing wheelies or carry a passenger because if you don't have enough slack in your chain it will be seriously stretched when your suspension fully compresses.  And NO chain is designed to withstand this stress.)  Also check the wear by pulling on the chain on the very backside of the sprocket.  If you can pull the chain away from the sprocket more than 1/16"(2mm) then you should consider replacing everything.   Also, raise your rear wheel off the ground, spin the wheel and listen for excessive noise, check for kinks, and check for loose or tight spots in the tension at multiple places around the chain.  Also inspect your sprocket(s) for excessive wear or damaged teeth.  If you find ANY of the above - REPLACE the chain.  If you don't replace it soon- you can expect to have more serious issues to deal with in the near future.
