Oil Condition After 1300 Miles

Hi all,

I am about to buy a Trimph Tiger 800 (2014) but I am a bit concerned about the engine oil. The bike has done all the services according to the manual and at official Triumph mechanic. I took the bike for a ride and everything looked fine. However, when I looked a the sight glass on the right side of the bike, the oil looked dark brown, definetly NOT amber and the viscosity was rather low. The oil has just 1300 miles but I am not sure if it's semi-synthetic or full synthetic. Anyway, my previous experince was with a Suzuki V-Strom 650 and as I nver had such oils even after 10.000 km.

Is this quite common for Tiger or should I be cautious with the purchase?
If it's common, then it's because of the position of the air filter (getting dusty) and the fact that Tiger's run quite hot engines?

Looking forward for any replies!

Many thanks and greetings from Austria,

George
