single can tenere and longitudinal balance?
I am planning to replace stock heavy dual exhaust from my xt660z
for single can which is saving around 5.5 kg, so quite a lot but wonder how that will affect longitudinal balance. Question for those who did this mod, have you notice anything negative in handling? I guess jumping especially can be a problem. Of course you can compensate this with luggage, but I'm talking here about riding unloaded bike.

No insight from me tremens, but i am Interested to hear how this goes. I bonded with my xt660z in Africa last year but found in too heavy to feel confident when properly off road (eg sand).

You jump yours? Respect ;-)

will let you know soon I guess
Yeah, bike is a bit heavy but when I go off-road I don't fill the tank completely
which is like over 17kg. This along with saving on single exhaust should put the bike in weight range close to Dakar bikes. Single can should give also more power.

thanks, good to know. Wonder if you noticed also some power gain or it's negligible?

It's all good ... any way to lose weight is a POSITIVE.
I doubt you'll feel an imbalance going from OEM to single, lighter exhaust system.

What brand Can are you using? I would hang onto original OEM exhaust in case you sell off later and want to put the bike back to stock.

The extra power you "feel" may be due to a less restrictive Can ... better flow,
more noise. (hopefully not too loud!) My Yoshi Can is not too bad but still prefer quieter stock Can ... but can't resist saving about 7 lbs. over standard.

Really hard to take weight off a bike!

it will be British MTC can, looks more or less like this:




and yes of course I will keep stock one for future when I want to sell this bike, but something tells me tenere is a keeper One of the last simple adv bikes on the market.

any weight loss is good, and no loss of stability should happen.
quite the opposite, less weight that's up high and on the very back of the bike is a blessing, less of a "pendulum" effect.

to gain power in meaningful way you'd need a very loud open silencer and jetting changes to match. IMHO not recommended in a bike to live with.

In my 600 motard i went with a semi racing silencer but with db killer baffle installed. Without the baffle it power fell on its face, bike was too lean.

dont fall into the common perception mistake that a noisy bike = faster bike

this MTC can has removable db-killer and I'll not remove it don't like laud bikes and I prefer silence when I ride trough woods or meadows. Electric bike
would be perfect something like Zero MX. Few more HP would be nice on tenere though.
