Not only did my smooth shifting machine become ultra smooth shifting, the engine actually ran even smoother and revved faster!
Long time motorcycle rider here. My current ride is a 2014 Honda Valkyrie 1800. A phenomenal bike it is! Fast, smooth and powerful. I have been a long time advocate of synthetic motorcycle oils for all my bikes. I've tried most of them... Castrol, Mobil, Honda, Amsoil etc. all great products HOWEVER, the moment I put Lucas Oil's 10w/30 full synthetic racing oil in my Valkyrie, WOW...what a difference! Not only did my smooth shifting machine become ultra smooth shifting, the engine actually ran even smoother and revved faster! It was most notable in the lower rpm range...ultra smooth! It is by far the best oil I have used in my Valkyrie yet. -Paul Roy, Wonder Lake, IL.
