Jack,

I charge $15 normally but $10 will do.

Email me if you are interested.

I can only advertise how much these sprockets improve the R259 motor!

It's really a must have. Much more fun and a lower fuel consumption as a bonus. It's incredible.
Take look here : http://www.spritmonitor.de/en/detail/461213.html
I have fitted the sprockets at 41000km. 1000km and 3 tankings later, my fuel usage has dropped by nearly 15% while it take more pleasure!!!

I am surprised at the low response here, at Boxertrix (UK) and the Pelican Parts board.

Here at Advrider there is incredible interest and excitement for a temp sensor spoofer yet little about a product that will really wake thier bikes up and pay for themselves over time with the savings in fuel.

Maybe there is a much smaller market than I anticipated or a reluctance to go inside the motor.


I would be very interested to know why.
My guess about the answer as to why, is due to a lack of understanding as to just what the product does. No, not the change in cam timing but a clear and definitive explanation as to how the horsepower and torque curves change using this product alone. I went to your site and the dyno runs include all of the modifications not just the sprockets. AND it took me a while to realize you were talking about the cam sprockets and not 'other' sprockets.

While these points may seem trivial they would greatly reduce the confusion as to just what is truly going on with this modification.

Now for racers or guys who are really knowledgeable about engine timing and tuning figuring out just what you're offering is easier. But most of the folks here on ADV don't know these details and without a better explanation that covers the reasons and the benefits, interest in the product may never reach 'critical mass' so to speak.

Just some ideas to ponder.

JJ

JJ,

Thank you for the feedback.

I will make changes to my web page to display the dyno charts and a better explnation of what they do.

Advancing the cam timing by the 9 degrees moves the power and torque curves 800 to 1000 rpm lower in the rev range dependant on the model.

After installing the sprockets and you look at the dyno graphs overlayed, essentially what you see is the torque produced at 3,000 rpm now is what was produced at the 3,800 to 4,000 rpm of the stock motor.

This gives the same throttle response and accelleration for less throttle opening and revs throughout the rpm range.

This in itself allows for the use of one gear higher for most riding and less need to downshift for overtaking solo or two up.

I have a set of these on my R1200GS along with a Techclusion... the difference is huge. I wish I had done this with my R1100S when I had it. Maybe I should buy a set just to have in the supply cabinet.

Sergio,

They are on special at the moment.

Everyone who installs them are more than happy for what they do for the way the bike now rides.

Just to clarify what Rocket Sprockets are for those who do not know.

They were developed by myself in 1999 and are 9 degree advanced cam timing sprockets for all R259 motors from the R850 through to the R1200 up to and not including the twin cam model.

They lower the torque and horsepower curves 800 to 1,000 rpm lower in the rev range or to the left on the graph moving the torque where you can use it better in day to day riding.

They improve part throttle response, help smooth the engine vibration and in most reported cases improve fuel consumption by up to 15% as reported by some customers all dependant on the model they are fitted to.

Hey lennie,

Thanks for the quick (10 days) delivery. Got the sprockets installed over the weekend. I have put in around 150 miles so far, and I am VERY HAPPY with the sprockets. Had no problems on the install, the directions were fine.
To those still undecided, these work as advertised. It is not a dramatic difference, but it is a definate improvement. I would do it again.

David

I am glad you are happy with the sprockets.

Enjoy the ride.

I am down to 13 sets of the seconds as they are steadily selling.
