125-200cc sprocket and chain question

I just bought a used 04 cr125 husky... immediately it needs new sprockets and a chain. has anyone jumped up to a 50 tooth in the rear and a 12 in the front? use the X chain or roller or non roller chain? the wife isn't thrilled about my purchase... so the cheaper the better lol. im a big guy...200 pounds and rank low on the skill setting. but I ride tight woods trails. any help would be great. thanks guys!

perfect

Good combination to go

I started with that one and eventually changed to 13 front and 52 rear this was in 125 trim

when bumping up the CC you can change

I am running now 12 front 47 rear.

Why didn't you just stay at 13/52, or go to 13/51, which is the same ratio as 12/47 but easier on the chain due to the larger front sprocket? Going to 12 just means you're going to wear out chains faster...

Just a mater of availability

I am in a part of the world where there is nothing for my bike and all components I have to get from America or Europe (and shipping to here is still a tricky business with a nosy customs in place) on my holidays to Europe I normally buy the wear parts from the shelf and it happen that that was what they had on the shelf at the moment I was in

not really aimed to get the 12-47 combination but 51 was not available at the time
