Probably will get one with the medium killer... cheaper and it´s for the mud and a bit of city, at the end. I´ll keep the original for the tech revisions...
Delivery 4 weeks including transport.
Nicely built, but it´s pipe has not the original welded nut, and so the complete line is supported just by cylinder bolts and rear "strip type" holder.
It seems a bit too weak. OK for urban ride, not for the mud.
Noise; It comes with a medium dB killer but seems to sound a bit noisy for urban ride .... being careful.
The raise in rpm is clearly faster, more reactive... healthy.
I haven´t ride the bike yet so that I cannot talk about power increase. But it seems a difference will be noticed, just after watching its much better breathability.
I´ll try to go for a ride and will drop a few lines here.
