Chain and sprockets - worth changing the gearing?

(1/2) > >>

Underdog1:
Whats the general consensus on changing the 18/48T gearing for a little more low end if i'm not going to be spending a lot of time on motorways?

Just looking at getting sprockets and chain so thought it was at least worth asking the question

Underdog1:
Thinking about dropping down to a 17T up front as Honda seemed to go this way for the Later models anyway. Would it be a 100 or 102 link chain I need? I know I can cut to length but will save me a job if I order the right size from here:

Seems cheap enough

hairygit:
Chain for an F1 is 102 links with 17/48 f/r sprockets, but I cant be sure K&F swingarms are same length or not.

Trigger:
Be careful on the K's. A small sprocket up front can put a hole in your crank case, due to back lash. Some 0 ring and x ring chains are too wide  ;)

not heard about that before but ill look into it. The DID VX chain is sold by wemoto as part of a sprocket/chain set for the CB750K so presumably its the right width.

If i stayed at the standard 18/48T gearing, do you know what the standard number of links would be? 100 link?

Seen a chain and sprocket set from a company called SNELL. Cant find a single scrap of info on them but the rear sprocket is anodised black which i like. Id feel more comfortable getting something from JT sprockets rather than an unknown but if anyones used them then please chip in
