ttr230 need wheel identification??

Recommended Posts

hi TT. i'm new to TT and just getting back into dirt riding.

i picked up a 2008 ttr230 with bad sprockets. i ordered a 14t front and 49t rear (as per the ttr230 typical upgrades). the parts arrived and today i was about to being the work.

i then realized to my horror that my rear wheel has only 4 bolt pattern.

i counted the teeth and there are 54?!?!? the diameter of the sprocket is 220mm {the replacement i ordered is 260mm}

the kid that owned it must have swapped a different wheel onto it and i have no idea what it is off of.

the wheel says J 18x2.15 786 DOT and also DID Japan 2.15x18. It has a drum brake and 4 bolt pattern with the bolts spaced about 80mm part.

does anyone know what kind of wheel this is or how i could find out?

thank you.

ok, that makes sense. i will get on that.

also, the front sprocket is held on only with the circlip...the retaining plate and 2 bolts are missing. is this something i should address. will there be a problem if i ride with only the circlip holding the front sprocket in place (i am guessing the previous owner did a lot of surgery on the bike lol)

For the front sprocket question, you need Part number 4AN-E7456-00-00 which is $3-4 plus two $1 bolts, PN 9702M-06010-00 or if you just take the sprocket to the hardware store you can probably find correct metric thread.

See if you can locate a shop manual for the bike.  You should be able to google and find a 2005 manual which will be good enough.  If you have trouble finding one send me a PM with your email address and I'll forward what I have.  Following the manual will not let you down.  Using the proper tools for the job is also smart.  For example, get a tapit wrench and feeler gauge set so you can adjust the valves.  Change the oil often.  A little basic maintenance and care will go a long way for having a dependable bike.  The TTR230 is a tough bike and a good one to learn on.

 Are you sure you have a TTR230? Is the rim aluminum, or chrome steel?

I downloaded the 2005 service manual. great tip.

i am 100% sure its a ttr230, here is a pic of it before i tore it down. it's a 2008 according to the VIN

not sure what the rim material is. i'll get a pic of it.

i saw a pic of a wheel from a 1976 TL250 on ebay and that looks pretty close

I bet I know what happened.I noticed on my TTR 230  that the spokes come loose really often.I bet the guy that had your bike before didn't notice and the hub and rim holes got rounded out and he didn't want to get a new wheel as they are pretty pricey.

oh yeah, and i also discovered that the chain on the bike is NOT the original 520 when i tried to mount the new front sprocket lol.

oh boy, this bike is the bride of frankenstein

 That's an aluminum rim, possibly an XT225 wheel. If you plan to use it you'll probably want to stay with the 428 chain size since you can buy 428 front sprockets but I don't think you'll find a 520 sprocket for that wheel.

i see, thank you motovita. i opened the 14 tooth front sprocket already (that's how i knew the chain was wrong) so i hope the company will take it back.

so would you know what tooth sizes would i need for the front and rear with the 428 chain in order to get the same 14/49 ratio that i wanted? 

the chain on my bike is a horror so i either replace the 428 or order a 520...either way i am buying a chain.

 You can do the math. 428 sprockets have a pitch of 4/8" (1/2"), 520 sprockets have a pitch of 5/8". Simply multiply the number of teeth by the pitch and find a similar size. It may be difficult to find a 428 sprocket as large as you want, Sprocket Specialists can supply them.

ok, great. thank you for the formula on that motovita

i've sent the dimensions from the sprocket i have to a guy at JT and i'm waiting to see what he says about finding something that might match up. 

i'll let you all know the outcome

i've chatted with a local guy who has an 18" XT rim with a 42-tooth 520 pitch sprocket in good shape still on it.

i checked it out and i think it would an XT500 with that kind of wheel.

does anyone know if this will this fit on my 2008 ttr230? the guy who is selling it seems to think so.

if it won't bolt right on then does anyone know how much engineering would be required?

thank you.
