thanks for reply, but here the proper winters will start from mid November and then too temp will be generally around 12-15 degrees till mid jan and then they will again start to rise so which grade should i choose
also some people are taking Duke heat seriously and saying hat after engine gets heated up they are experiencing drop in performance and harder gear shift does this also mean its better to stick with xxw50 as it will be better in dissipating heat then xxw40?
This looks like a million bucks, specially the silencers, do you know the details i.e. make, model price , where to procure etc of this silencer and do they add to exhaust note and power delivery?[/QUOTE]
Im gona use 15w50, 300v factory it seems like a good balance and good performance but i think you'll void your warranty. That picture's actually just a concept. Seems its akrapovic, i haven't seen any exhaust like that and i highly doubt it is manufactured. The bike is a 125 as u can see the exhaust coming from the RHS unlike ours, or that may just be a mirror effect.


, thanks to all you guys i've made my decision to buy the Duke, thanks once again
