Hi all

Looking for some advice on my beta 250 evo 4t 

what are your views on dropping a tooth on the front sprocket ie what will I gain or lose from it 

thanks 

What are you trying to achieve? 

I'm not sure if it is the same gearing, but I went from an 11 tooth to a 10 on a 2016 300 4t.  I think it made slow tight turns with clutch slipping easier.  It was also less abrupt when letting out the clutch. The bike picks up less speed when going over a series of obstacles close together.  I tried a 9 tooth and it made tight turns even easier but killed some of the snap used to get over obstacles. 

I did this on my 300 4t, it main a noticeable difference it really tight sections and improved how the bike worked at slow speeds, If I need more power or torque there is 2nd gear (also more useable now)  

I've had a few 300 4t s.  Always dropped to a 9 on the front & left the rear as standard (43 ??). Lots more manageable in bottom,  & 2nd can be used more frequently.  Worth a try, as cheap to do. Also, less likely for an infamous 4 stroke cough, as usually there are a few more revs on . 

I have had several of the Beta 4t trials motorcycles and have found the stock gearing to be the best.
