Time for a new drive train and I'm open to opinions

Recommended Posts

Ya there are plenty of topics about this but as the title says :)

CFR250R setup for woods/fast to hard technical single track (no racing) in the PNW and 13/51 (not changing gearing)

I've got a budget of say $300 CDN.

Current setup has been on for about 150hrs and thought I had written what it was in my log book be didn't and if my memory serves me correctly. a Renthal front that I had to place after about 10hrs with a Sunstar 520 due to quick wear, Renthal Ultralight rear and a Renthal 520 R1-MX non o-ring chain. Clean, lube and adjust as needed.

So what I've got in my cart

Sunstar 520 Front for $24 CDN - Wear has been great.

Sunstar 520 Works-Z Rear for $118 CDN - Based on how well the front held up, I expect this to hold up well too.

Renthal 520 R1-MX chain for $112 CDN - I like a non o-ring chain and this has held up extremely well.

Renthal steel front and a Sunstar steel rear sprockets and a DID VT2 X-ring chain has proven very durable on my CRF250X,

going on 3 seasons and close to 3000km on the combo and barely showing any wear, the chain never needs to be readjusted.

 

Same sprockets on my YZ125 but a 'supposedly' stronger DID ERT2 that simply does not last, 

switching over to a VT2 for next season.

 

On a budget, IMO a better chain used on 'average' quality sprockets will last much longer than the other way around.

For the best in longevity, go with what you like up front, a SuperSprox rear, and a quality X-ring chain.

Primary drive or other cheap steel sprockets and a did vt2 chain is the best bang for your buck as it last a long time, not quite as long as the super hard long lasting steel sprockets but the cost is so much lower its still a better set up. 

I think the crf has clearance issues with wider o/x ring chains so I'd go with the skinny vt2.

Unless your a pro mx racer forget about running non sealed chains they just don't last offroad and wear the sprockets out quicker too.

So in short spend  more on a good sealed chain and less on fancy sprockets.

Ive been doing some more research and yes I agree with a quality chain and looked at the Regina, DID and RK but the Sunstar is rated at like Tensile Strength of 8970 lbs. Really don't know if it makes a difference but most of the others are around 7900.

Otherwise someone else reminded me about the Ironman's, a bit more $$$ and might go with these front and back.

Damn like trying to decide on tires but more expensive and I'm expecting a longer life :)

Thanks for the input so far!

The tensile strength in this application is pretty meaningless.  What is more important is just the overall quality of the chain.  With standard chains I've always had good luck with DID.  Regina is probably the best chain you can buy, the gold standard in chains, but they are usually more expensive.

After my DID ERT2 wore out sooner than expected I purchased a less expensive MSR gold chain just to finish the season,

MSR reboxed chains are 'supposedly' made by Regina but obviously it wasn't one of their top of the line chain but rather a price point product.

It wore out about twice as fast as the ERT2 and had a huge amount of side play in the links.

 

As mentioned in an earlier post, after almost 3 seasons on my other bike a DID VT2 has proven to be a great value and well worth the premium price.

Again thanks for comments and I should be out ripping:)

I'm in no huge rush so I will eventually check with my local shops to see if they can come close to on-line prices but

Another place I occasionally buy from on-line in Canada and the Dirt Tricks Iron Man.

Clipboard01.jpg.766d9fcc183176ee4f9f3960ca271b1f.jpg

Then checked with RMATV and our exchange rate SUCKS ($1.31) so almost the exact same price Canadian and would prefer to buy Canadian anyway :) so now going back and forth on the Dirt Tricks vs Sun Star sprockets.

I'm still leaning towards a non o-ring chain and trying to compare a lot of options/prices. I know how the Renthals preform and some examples in the $120 range then around $200 plus for 4 brands . I don't mine spending the extra $$ on a quality parts so the question is regardless of manufactures is $200 plus chain really worth the $$ if the sprockets are also quality for longevity and am I answering my own question?

Haven't washed the bike in a while cus I'm been slacking and not riding much. Full cleaning before I replace the drive train and putting on a new rear for the PNW fall riding :)

I got a full season out of a $20 ebay chinese gold chain a few years ago.  I wouldn't recommend it, but that just illustrates how important taking are of your chain is.

I'm currently running the Sunstar front, and Works-Z rear sprockets and am extremely happy with how they are wearing.  I ride MX only, and usually got  ~40hrs out of the rear sprocket (I've run quite a few different brands) on a 250f.  I now have a 350sxf, am at 40(ish) hours on the set now and they are showing very little wear.

Chain wise, I've always been a DID ERT2 guy.

Looks like you've never washed that thing 😂😂 lot of hours on that chain plates are flat. Gotta watch master clip if has one. Guide will wear them thin and  chain comes apart

If you buy an  o-ring chain and steel sprockets you should easily get over 100 hours out of them, I get about about 5 x the life of the same setup with a standard chain in the conditions I ride. Sand and a 380 will demolish a standard chain in just a few rides. My $50 o-ring chain is due for its first minor adjustment now at 30 hours.

Agree.  Steel sprockets and an o-ring chain will way outlast a non o-ring chain.  The initial cost of an o-ring chain is higher, but you should get 2 to 3 times the service life.
