I have a 2004 Triumph Speed Triple 955cc water-cooled triple with wet clutch and trans sharing common oil supply.The manual clearly states to chang the original factory oil at 500 miles and that a full synthetic 15W50 only is recommended.I purchased the BMW 15W50 full synthetic oil at $7.50 a quart.It is labled as being made by Golden Spectro for BMW motorcycles.I immediately noticed that the bike became harder to shift after reaching operating temperature and that I experienced three false neutrals in the space of only a 15 mile ride yesterday.The oil only has 250 miles on it now.The bike has only 750 total miles on it but it shifted great on the break-in oil from the factory.I emailed customer service at Golden Spectro and they recommend that I drain this oil and use their Spectro 15w50 full synth.They said that even though this oil that I am using states Spectro as the manufacturer in small print on the silver bottle's label that it is in fact made by Valvoline or Castrol.Castrol "synthetic" is not a genuine synthetic-just marketing crap-I do not believe that Valvoline "synth" is any better.I am very disappointed that I shelled out $40 for this very average lube.Do Not Let This Happen To You !!
