Evo 4t chain

Recommended Posts

 

Dont laugh, I feel pretty stupid asking this. It's a newbie thing.

I'm going to replace both sprockets and the chain on my 4t. Is there something special about a 4t chain? Looking on Ebay there are tons of Beta specific chains listed but they all say "not for use on 4t". Trials Superstore and The Trials Shop have chains, all are listed as 520 chains, but all have different numbers of links. What chain do I need? I'm using 10/42 sprockets.

Don't know but my guess is the length between the Counter shaft sprocket and the rear wheel sprocket is different between 2T and 4T.

 Well if you are ordering the same sprockets then count the number of links on your existing chain. It`s much easier to own a chain breaker, then you can cut a chain to fit. Just order a chain at the best deal, longer than your original.

yes its not a special chain but is a special length you need a half link fitting to get the correct length 

Your Beta importer should have this chain ready to go on the shelf OEM regina very good quality last ages

I counted the links, there are only 50. So will any 50 link 520 chain work?

That would be 100 link chain.  You werw counting 2 pin plates.

 So know you wonder with the above comment if it was 101 with the half link stock. So you buy a chain breaker and a 102 or longer chain.

probably 101 links to start when new your chain could have been shortened after it stretched

Thank you all for helping me out.  I have a chain ordered, a 1/2 link is another story.  They sell for 7-9 dollars but they want 25-32 dollars to ship. I need to find one with a more reasonable shipping cost. The chain on the bike dosen't have a 1/2 link so maybe I can go without one.

if a previous owner has altered gearing by + or -1 tooth it might not need half link
