Beta Evo 4T Gearbox Oil

Featured Replies

Doing my first oil change on a used 2011 Beta 4t. Manual says to use .81 liters or 810cc, my dealer claims to use .9 liters or 900cc.

I know it is only 90cc difference, just would like to know which amount as I don't want to overfill the gearbox and cause any problems.

Many thanks

Tom

I don't mean to be pedantic if it's purely a choice of words, but its a 4 stroke, so not strictly gearbox oil as it's a sumped and pumped motor. Just want to make sure you're sticking in the right oil and not gearbox oil! I can't anwer your question though as mine's a 2008 which is 900cc.

Bongo its the same lump! Lampkins told me 800ml. But the real question is 10w 40 or 15w 50 fully synth???

I have a 2009 250 4T and I always use 900cc of 15-50, usually Motul 300V double esther, and have had no problems.

PS the oil filter is a standard HF207 much cheaper than the Beta filter.

i wouldnt worry...if your over full a tad..youll find the extra in the bottom of your air box first time you run it down a trail.

iv been using motorex..pricey. but worth it.

Suzuki DRZ oil filters are the same as Betas. i switched to cleanable type..30.00 but worth it.

Too right Chuck. Or puddeling in the rubber boot that goes from the air box to carb.

Had that in my airbox....

been there already...lol... and learned. scared the crap out of me..it was the first break in oil change..on my 2013..

4 strokes can run on a lot less oil than the manual says, just gets dirty faster

I think in a lot of motors less oil can be better for performance
