Unsprung weight
Was just thinking about the rear suspension on the Scoot (Which I have upgraded to YSS Shocks). The motor, exhaust, drive-train and Rear wheel are a lot of unsprung weight. How much difference could a substantially lighter exhaust can make? The stock one is like having a cinder block hanging off the side of the bike. Would losing 4-5lbs of weight there make a noticeable improvement? Small amounts make a huge difference on Mountain bikes.

Re: Unsprung weight
I put on a malossi exhaust that was about 7 pounds lighter than the stock exhaust. I didn’t feel any difference at all dropping the weight. In my opinion, I will always put an aftermarket exhaust for only two reasons: one, it looks better and two, it sounds better. That’s it.

Re: Unsprung weight
Yep, those generic cans are lighter. None are tuned to your engine - which frequently leads to loss of the low-end grunt Honda designed into your stock exhaust - but hey - the mounts are changed so they can fit everything from a Ducati to a Sear's riding mower.
For most riders: the generic chrome can with an Asian or Italian sticker AND louder equals faster --- in the head.
Plus - you get to spend a few 100's on your scooter! That must be worth something!
Pretty cool to see one more rider admit they do nothing for the scooter performance or ride! Very cool.

Re: Unsprung weight
Um, you might want to go troll the exhaust performance threads and pontificate there. I was specifically addressing suspension improvement, not making my already F.A.F scooter even faster with a lighter exhaust.fish wrote:Yep, those generic cans are lighter.

Re: Unsprung weight
Running YSS shocks, no difference between the stock exhaust or the Malossi in terms of ride......

Re: Unsprung weight
OK thanks. i thought it could be a bit of stretch. My bike rides really well anyway with the YSS shocks I have so I'll call it good.Jge64 wrote:Running YSS shocks, no difference between the stock exhaust or the Malossi in terms of ride......
