I'm the owner of a brand new ER-6n, I ride about 2000kms (1200 miles) with my bike since I bought it. I love it but since last week I think the bike have a problem with deceleration. I'm not sure it's a problem, maybe it's normal with the ER-6n.
The problem is when I release the throttle, it give a small hit. I mean, when I'm on the highway, riding @ 100 km/h (60 mph) if I release the throttle rather than decelerate gently, it gives a blow and then it gently decelerates.
It's happen at low speed too, first time I notice this it was in a traffic jam, every time I removed my hand from the throttle the bike gave a small hit, since in a traffic jam there is a lot of acceleration/deceleration I received constant kick from my bike.
It's really hard to explain, especially in English since it's not my first language. But if some Er6n owners here understand what I mean, can you just say me if your bike react the same way?
Deceleration was much softer on my previous bike, there was no such hit/kick when you release the throttle.
