I USED to agree with you. I felt a little instability in fast sweepers, and hated some sections of freeway where the rain grooves induced wobble. I was careful with the throttle in curves, and never lost control, but sometimes I had a pucker moment. After reading the posts here, I began to recognize that there MIGHT be a simple way to make my ride both smoother and safer - if, indeed, I was experiencing "wobble".
OK, $289 to improve my $20k motorcycle's handling and safety - maybe. Decided to give it a try, and placed the order. Installed this beautifully machined, straightforward mod myself (a rare thing for me) yesterday and took it on a familiar mountain freeway today. This road is routinely driven at 70-90mph by the cagers, and has some wicked rain grooves in sections. I've ridden it enough to be very familiar with how my bike behaves on it......rode it just a week ago.
Today was a whole different experience - it was like a new bike, a '09! The instability was gone, period. I even tried to induce it to no avail. The bike is substantially better. No more wobble - even running 20 mph faster than before. The bike holds it's line in turns even with sudden, severe throttle changes. The "on rails" description is true.
Was it worth $289 and a hour's time? ABSOLUTELY. To me, it was a bargain. I believe it makes my bike safer, and it certainly makes it less stressful in the turns. I wholeheartedly recommend this product, even if you (like me) are not UNhappy with the stock setup. IT WILL MAKE A NOTICEABLE IMPROVEMENT.
