changing front sprocket only, do I need a new chain?
2010 Ninja 250. ~1,000 miles
Yeah pretty much my mechanic is awesome, but I think he tried to upsell me today and pretty much said I'm going to need a new chain because the sprocket won't fit... I doubt that. I need a definite answer guys. THX!
The stock front sprocket is a 14 tooth sprocket so going up 1 tooth shouldn't be an issue.
LOL and as was pointed out 520 is a good compromise of strength and rotating mass and whenever people list their mods as a "520 conversion" when they had a 520 width chain and sprockets to begin with I laugh out loud. It's like putting new tires on your car and toting you put a rubber tire conversion kit on your car....
Most any 250cc-750cc or so bike on the road these days take a 520 series chain/sprocket setup. Some of the 600cc+ rides use 525 series and some of the torquier rides run a 530 series.
