This would depend on what type of oil you will be using for your premix. The oil base stock is either petroleum, semi-synthetic or synthetic oil and is mixed with gas at a ratio ranging from 16:1 (petroleum) to as high as 100:1 (synthetic). My 2 stroke I have is a 2001 Kawasaki KDX200 that I run Yamalube 2R at 36:1 with no problems. Although synthetics say you can mix them at 100:1 I would not, that seems way too lean to me.
Rough riding requires 32:1 and normal riding 40:1.
Depends on the rider. But the answer should be, "No".
ITS 200 pounds.
If you mean a CR 125R you have to mix 2 cycle oil and premium gas
It will do about 120 kph or 75 mph.
About 80-85with a fatty pipe, about 76-80 stock.

I have to assume you're talking about Standard Byke's 125R vs. Standard Byke's 250 Series frames, correct? First off, the intended purpose of these two bike frames are completely different. A 125R is a racing frame (thus the "R" in "125R") while the 250 Series are Freestyle frames. As far as "size" goes, the 125R and 250 come in five different sizes: 20", 20.5", 20.75", 21", 21.25" (250 Series only) and 21.5" (125R Series only) top tube lengths. So to answer your question: A 125R and 250 are the same size if you compare the same two sizes, but the 125R comes 1/4" longer than the longest 250.
between 135 and 140 between 135 and 140
Gearing ratios indicate it will go aproximately 110km/h (just under 70mph) before hitting redline. More than likely it will go 100km/h (62mph) downhill with a tailwind at the most.
i have a 1998 cr 125r and im guessin urs should be close to about half a litre. there is a bleeder screw at the bottom of the case, take that out, fill it until oil spills out then replace the screw and you should be good. good luck
