Hi,

Just wondering if anyone can advice me as to a good replacement chain/ sprocket set for the NSR150SP model sold in Australia.

I know that DID chains are good however have yet to find one that will fit the NSR150SP.

Is it a good idea to change sprockets with the chain?

If TYGA sell chains, I might buy the pipe and chamber set to reduce overall shipping. Which would be cheaper that buying and shipping individually.

I appreciate any sort of help in this regard,

Thanks to the guys at NSR-World this is a one of a kind resource.

Hello Q, and welcome to the Forum.

First off, it's always best to replace the chain and sprockets together. Worn sprockets can seriously reduce the lifespan of a new chain.

I don't know the spec of the NSR150SP chain, but I doubt it's anything out of the ordinary. Do you know the chain size? You should be able to buy a pattern chain from most manufacturers... anything from a £10 budget non-O-ring to a £50 gold X-ring, and anything in between. It will just need shortening to the required number of links, which any bike shop should be able to do for you if you don't have a chain splitter.

For example, I use an £18 non-O-ring 520 chain on my MC21. I buy one 112 links long, and then shorten it to the required size (currently 107 links I think) to work with whatever gearing I choose to run. I tend to replace my chain twice a year, or swap chains when I change gearing, so they don't get too much use, but some choose to run £50~60 chains as they may be fitted for a year or more -- each to their own.

Thanks for the reply Andy,

I think I'm after a 520 108 link chain.

If it is a standard 520 chain, almost all your bike stores should stock them. Pop into a bike store and just ask them what they recommend size wise.

A 520 o-ring chain retail is around the $90 mark, sweet talk or buy it on sale and you get it for $70.

As Andy mentioned, change out your chain and sprockets at the same time.

Cool thanks for the tip,

Can someone also advise me as to the tools and procedure for changing the chain? Is it better to get it done professionally, considering the labor fees? I am aware that a C tool is required however, I do not have one myself.

Thanks.

chain and sprockets on a normal double sided swingarm, I have done before, but not on the pro-arm.

I prefer to use a rivet link, a clip link is no problems, I can't see the SP generating too much power I can't remember which way the clip has to be mounted though.

If you're reasonably competent with tools that I would suggest you have a go yourself, grab a bike mate friend that can help you, otherwise take it to the shop.

You would need:

Grinder + chain breaker
rear stand
any other specialist tools
allen keys
pliers and general tools

I'd probably have expected the chain on the 150 to be slightly smaller than 520, but I can't remember to be honest.

I use a split (spring) link on my MC21 with no issues. It's not changed a lot, but it would be a pain in the ass to have to rivet a new link each time it was changed. A 150SP certainly isn't going to stress a 520 chain/split-link if that is indeed the size required, and a split-linkmakes the job a hell of a lot simpler and quicker.

A Pro-Arm can only make the job of replacing a chain even easier in my opinion.
