I had 07 Kawasaki er 6 n.
I modified mine for track day use.
-Matris front suspension
-Leo vince slip on (without db killer(loud!!))
Anyway, what i wanna say is: the engine is AWESOME!!!!!!!!!!!!
During two summers 07/08 i did about 3500 km of full on track miles with it.
You can't break one of these. If i had a garage i wouldn't have sold mine, instead i would have build a rally bike out of it.
So please man build it.
By the way my Er had 77 horses and 69 nm of torgue, with modifications. So it should do gravel road power slides
What kind of track bike you got Lukas?
