I love my 2009 Yamaha R6 but like all things I own that consume gas I wanted more power and acceleration. After some quick research online on how to squeeze as much inexpensive horsepower out of my R6 as possible, I came across the Vortex/Regina Sprocket Power-Up Kit on www.KneeDraggers.com. After reading a few rave reviews on this sprocket and chain modification for the R6 I purchased it from KneeDraggers for $229.00 with free shipping and handling.
Vortex/Regina Sprocket Power-Up Kit
The stock 2009 R6 comes with a 525 chain size. The Vortex/Regina Sprocket Power-Up Kit is a 520 conversion. That might not seem like much but every little bit helps squeeze out some hidden acceleration. As for the back and front sprockets I decided to go 1 up/2 down, any more than that and I would be spending more time shifting than necessary.
I didn’t have the tools (or experience) to perform the 520 conversion so I took it into my dealer (South Seas Honda Yamaha BMW) for a professional install. It only took about 2 hours to install so with $150.00 spent for installation the total cost of this 520 conversion came to $379.00. And let me tell you it’s worth it!
Acceleration from rest is remarkably faster than the stock setup and roll-on acceleration pulls just as hard. Lifting the front end up is considerably easier in first gear and even highway speed wheelies on the 600 are now possible with the right amount of finesse finesse!
However, with the new sprocket gearing your speedometer and odometer will be completely off. With my 1 up/2 down ratio my speedometer was reading roughly 12mph faster than it actually was, which obviously threw my odometer readings way off too. To compensate for this I purchased SpeedoHealer from HealTech Electronics Ltd. for $115.00.

SpeedoHealer is one slick piece of electronics. It’s a plug and play device that plugs directly into your 3p plug. Cailbrating and programming your SpeedoHealer to your correct sprocket gearing is fairly straightforward thanks to their online calculator. Once you have it set up properly you can regain 100% accuracy in your speedometer and odometer readings. In addition, SpeedoHealer has a Top Speed Memory button you can press to display your last true top speed on your speedometer.
SpeedoHealer will fit almost every bike on the market. If you have an older bike and aren’t interested in resale value you can just have someone pace with you to get your true speed. However, if you’re thinking about selling your bike someday the $115.00 price-tag is money well spent to keep your bike from depreciating that much faster.
So there you go. If you have a 600 sportbike I feel the 520 conversion is well worth the added performance. However, if you have a litre bike I would probably stick to your 530 (or whatever you have) over the 520 conversion. It’s too much wear and tear with all the horsepower a litre bike puts out in my opinion.
