Here in italy the 2015 models have 5.4 rear spring that's OK from I think 80 to 90 kg.
I'd think you will need a 5.6/5.8.

I'm in the U.S. and found the information on the B.Y.O.B. website.

The stock Fork Springs are .42kg (175-190lbs)

.38 kg (140-154 lbs) RR2t (AB-12048-38)
.40 kg. (155-174 lbs) RR2t (AB-12048-40)

.44kg (191-220 lbs) RR2t (AB-12048-444)
.46kg (211-230 lbs) RR2t (AB-12048-466)
.48 kg (231-250 lbs) RR2t (AB-12048-488)
.50 kg (251-270 lbs) RR2t (AB-12048-500)

Stock RR 2-Stroke Rear Springs are 5.2 kg rear spring set for 185-199 pounds

4.6kg (140-154 lbs)RR2t (AB-10150-466)
4.8kg (155-169 lbs)RR2t (AB-10150-488)
5.0kg (170-184 lbs)RR2t (AB-10150-500)

5.4 kg (200-224 lbs)RR2t (AB-10150-544)
5.6 kg (225-239 lbs)RR2t (AB-10150-566)
5.8 kg (240-254 lbs)RR2t (AB-10150-588)
6.0 kg (255-269 lb)RR2t (AB-10150-600)

So if you weigh 185 - 190 lbs with your gear on, you are the guy the bike is designed around... I have a 300 RR Race edition on order and was told to go one spring lighter than the chart says for the forks, and to follow the chart for the rear spring.

great info, thanks keith. does anyone know if there are rear shock springs that are interchangeable with the beta?

i need to go up to a 5.4 or 5.6 but they won't be arriving in australia for a few months.

i checked on an ohlins spring but the problem is the shock goes so close to the air cleaner box that it looks as though a lot of springs will be too wide.

Check KYB springs.
Don't know for sure but maybe they can be used.

KYB will work but OD is a bit bigger and may rub airboot. Any Sachs spring, even from an old Husky or GG Sachs is the same.

thanks guys. a local suspension shop says he's got a spring that will do the trick but it's a fair bit more expensive than the genuine beta shock so wondering if i should just wait till their new stock arrives in a months time.

it's so weird having genuine parts that are so much cheaper than ktm ones were.

I am picking up my 2016 300 RR tomorrow. In the meantime, I have been looking for some heavier Sachs compatible shock and fork springs that will be more appropriate for my weight. I haven't really found any place online that seems to have what I need. I am in the US. Does anyone else know where to buy different springs online?

Thanks much!
