Hi all,

Just wondering if anybody has played about with changing the sprockets on a Hyper. Smaller on front larger on back for more wheely power.
How far can you go? say 1 smaller on front and 2 up on back.Does changing affect the speedo reading.
Any views / experiance on this anyone???

Have you tried to search "sprocket" on this forum?

A few threads worth checking out in there

I have a -1 front with a stock rear. I love it. 1st-3rd the front comes up. I havn't noticed anything in the speedo change. I'm usually within a mile per hour of the radar signs.

The standard gearing has long legs to keep the bike up over a range of speeds and I would not want to change. There are other ways to get a bike up, rather than just twisting the throttle. Have a go at exploring these and improve your riding skills repetoire.

If you are subtly eluding to clutching up the wheelies, the dry clutch doesn't seem to take to that very well. Certainly not as well as the wet clutch does.

I think the dry clutch bounces too much.

I can power up 3rd gear even at 4600'MSL. Once you hit the balance point, you just ride............and it doesn't beat my bike.

I'm running a 1 tooth larger on the rear, 15/43 so now I can pull 6th to redline, but I do have a strong motor, if I had a motor closer to stock I would run a 15/44, that way you still have some freeway legs. I would not run a 14t on the front, especially with a #520 chain for strength issues. Aloha Alex

I beleive -1 on the front is the same as +3 on the rear.
Ducati's used to have 14T front, but are now leaving factory with a 15T to meet the restrictions and euro norms.

I went for a 14T and I'm very pleased with this mod. Makes the engine even more hooliganish, and the wheelies are still a joke.

The speed sensor is at the rear wheel, so whatever you change on your drivetrain wont have any impact on your speedo reading.
It will still read the same speed, within the 8% error from the ECU

Get in touch with JCpakbikes, he had some great deals on front + rear sprocket + chain.

I never use the clutch on any of my bikes to pull up the front. (unless riding over a fallen log)
You do not need excessive throttle/power or clutch drop to whip up a bike.
I find that once up, the lower geared wheelies are much harder to control, anyway. Standing up on the pegs is my preferred method for launching and higher speed wheelies.

If you have the time, hone the skills on a dirt or trials bike.

Alex,

So you think I should go up 2 on the rear to pull redline on my Hyper??

I was thinking only 1 because of Arizona having those LLLOOOONNNNGGGG, straight roads with higher speeds, I don't want to be running too high of an RPM for longer times.

Your thoughts??

I went to a stock 848 rear sprocket -2 and took a link out to keep it off the rev limiter on long straights, I'm not into wheelies but still can if I want. I also get better highway milage.
