I saw a great deal on ebay for JT 15/45 (both steel) but the chain is a Bikemaster, which I'd not heard of. It's a 520 O ring
The majority of my riding is city, I'll give it a good accelerating blast around the ring roads, but rarely am I over 100mph, if that changes anything???
Also saw a 'Hyperfast' kit which uses Vortex sprockets and an RK chain. They didn't note the rear sprocket size but I assume its the same 15/45 set up
Is 108 enough considering the sprocket change? Or do I need longer linked?
108 links should be enough for a -1+2 sprocket set up. typically if you buy a set they will be sure you have enough chain to fit it to the bike.
vortex makes good stuff but i would avoid the aluminum sprockets. they will wear much faster than the steel.
also its my advise to just get an oem 530 pitch. paticularly for just regular street riding.
i know the 520 does weigh less and that added acceleration potential is appealing but its a very small boost. guys who are racing or doing track days like this mod because the lighter 520 set up does cut a couple tenths of a second off the total time it take your bike to accelerate up to speed. multiply that by how ever many turns are on the track you accelerate out of and you can shave seconds off a lap time. however, on the street your not trying to shave seconds off your commute to work or the trip to the corner store or even your time thru your fav canyon.
so imo there is really no practical reason to put a 520 kit on a street bike when a 530 is oem. these newer 520 kits are strong enough but regardless of tensile strength the 520 is still less material doing the work of the 530. its going to wear a lot faster. thats the trade off and imo its a bad trade for a street bike.
RK is def a better product than bikemaster. im not saying the bikemaster wont do the job but i can tell you its not as nice as the RK on any level.
post links to the kits youre considering n i will be happy to give you my 2cents on them. as i mentioned tho imo its best to spend the extra money n get something you can be sure is the best. did, rk, ek. sunstar, jt, driven, vortex.
thing is im sure a bikemaster chain is decent. im sure it works at an acceptable level when new. lets keep in mind the end game when you get closer to the end of its life. when youre trying to get those last few thousand miles out of it. in this portion of a chains life personally i would feel much better riding on a rk,did, or ek brand chain over anything budget friendly. its important anytime, over or under 100mph. if a chain breaks mid corner it is sometime a violent occurrence. it can easily cause you to lose control and should it happen as youre accelerating out of a corner can easily cause a wreck. there is a chance it can break and whip into your leg with enough force to cause serious damage. its not uncommon if a chain breaks for it to get wadded up in the front sprocket jamming and breaking the engine casing. thatd likely cost more to repair than the bike is worth or at the very least a tremendous amount of work and a fair chunk of cash.
of course these things could happen with a rk, did, or ek chain too, but imo if they are properly cared for your chances of this happening are, imo, much less likely to happen on a top end chain vs a budget type chain like a bikemaster. those are just my opinions. ive never researched the bikemaster chain and like i said they make decent products. i very much doubt they manufacture these chains tho. im sure they are made somewhere in china and branded with the bikemaster name n sold. im betting like most things in life you get what you pay for. chains are important. they arent like a set of oem replacement bikemaster mirrors or footpegs etc etc. this is a part than can cause you or your bike some serious harm if it breaks n for that reason much like tires and brakes i think you should drop the extra 50$ n get something you know is the best. something you can ride on without worrying if its going to fail at the worst possible time. these are high performance machines and in some places paticularly require high performance components. even if all you do is commute n hit the occasional sunday canyon.
