you need to buy what they call a tuner muffler. They run from $129.99 and up.
there is x18 x19 and x22 they are like sport bikes but smaller the x22 is 27in seat height
Maybe because they don't like the noise.
It is possible that a part of the EGR valve has fallen out. This will cause a very loud exhaust noise.
Bianchi offers a range of bike models including road bikes like the Oltre XR4 and Specialissima, as well as mountain bikes like the Methanol and Grizzly. They also have hybrid bikes like the C-Sport and Impulso.
if the noise comes from the front end while you rev the engine, and not alot of sound comes from the tailpipe, check the exhaust from the front back for cracks or breaks. it sounds like an exhaust leak to me.
I am 6' tall and I have yet to find a comfortable sport bike to ride. I currently ride a 2007 GSXR750 and it is not to bad but, I don't think sport bikes are really built for comfort. If comfort is a necessity you might look at a sport touring bike or something with handle bars rather than clip-on steering like most sport bikes have. For short trips like 200-300 miles in a day, you can suffer through it on a sport bike but, for trips longer than that, you will be ready to get off of it. You can change the seat, grips, windshield, and whatever else you like but, it wont make a difference. Sport bikes are built for speed and hanging curves and if you like them then you will have to endure being uncomfortable.
Sounds to me like HOT exhaust cooling down.
check your engine for a cracked manifold (covering of the engine parts and cylinders. also look for any exhaust leaks. it sounds like the exhaust noise isn't making it to the muffler as it should and instead is coming from the engine directly.
That is kind of a tricky question. Dirt bikes encompass any bike that is ridden off road plus what are known as dual sport bikes. Most of the manufacturers categorize their dirt bikes as motocross or off road. Basically "dirt bikes" break down like this; 1) Motocross race bikes and woods race bikes. These are both liquid-cooled bikes with aluminum frames and racing suspension (compression and rebound settings, long travel, etc.), the woods race bikes just have some minor changes such as a wider gear ratio, a heavier fly wheel, bigger tank, lights, softer spring rate, etc. 2) Trail/play bikes. These bikes have air-cooled engines, steel frames and much less suspension than the race bikes. 3) Dual Sport bikes. This category is everything from Woods race bikes with a dual sport kit installed to make them street legal to production dual sport bikes such as the Honda XR650L and BMW 650GS.
probably answered your own question.
This sounds like an exhaust leak (which will only get worse with time).
check the cadillidic converter under the car.
