Time to get a new chain and sprockets

Seiki · Admin

Give B&C express a call , see what they have . That's where I got my Renthal o ring and sprocket . Keep in mind though theres VERY few options for the DTR wheel

ah thats fine then.

i was getting worried mine started on one notch b4 6 ... are chain fine to take links out? i was gonna do it with my old chain but the sprockets were ****ed anyway ...... i heard chains get weaker when you take links out? :S

Seiki · Admin

As long as it's a quality chain like OEM mate it's fine to take one out

and to answer what DTpower wanted :D

16 front sprocket
57 rear sprocket is standard

taking one tooth off the front will drop top speed but will improve acceleration
adding one tooth to the front will drop acceleration but will pull to a higher top speed.

look on ebay, type in: did dt 125 chain sprockets
i would find some descent kits for you .. but your in sweden!

thank you Craig and Seiki.. the shipping from UK to sweden is about £ 15 but it's still cheaper on ebay than over here :D yamaha wants about £60 for a set with a non o ring chain the set is probably **** anyways... i could check on some german sites too as the DT 125 is quite popular in germany..

Wish me luck guys! LOL

forgot to ask about your chain size? i see many sizes 420 - 480 -520 ... what size did you get on that iris chain Craig?

dt standard is 428 pitch i have seen 520 convershion ksets tho and with a decent oring 520 chain will last manny miles

craigbulmer · Guru

Dickhead · Nonce

520 is a bigger pitch chain found on rs125s most 250 motocross bikes basicaly a fatter bigger chain my dt250 in my dp is a 520 chain also you get fancy sprockets etc
