415 chain conversion kit

[aftermarketcycles]

(4) 17/54 kits ready to ship as of today - these are very successful in every race club running 250's and we also confirmed this kit is the same for the Ninja 300.

I have more 18 fronts being made but I don't want to promise any eta's.

i see, thanks for the info
i did a quick search and found this

i bet you all know this but it was a good read for a noob like me...

what would be the durability vs a 520 chain ?

[mgentz]

I like this idea but I was worried about durability as well. Now I have a non oring 520 but I am still considering this....

They are the same for the 300, but remember that the gearing is different so stock ratio is a 17 front and 51 rear.

Do you offer a 17/51 415 kit?

I'd prefer the smallest sprockets available (14/42?) since the smaller sprockets should offer even less weight.

Nothing?

I think I can answer this one. The front sprockets are the ones that hold up the orders. Rear sprockets are made to order fairly quickly. I had Mark send me a 50 tooth and a 52 tooth rear. I actually received the rears the day before I got the front.

Thanks for the heads up. If he can get different front sprockets (even if it requires a pre-order) then I'd be all for making an order. The last thing I want though is to run a big front sprocket and a larger rear sprocket just to keep the same gearing as a 15/45.

If the 'sales pitch' here is less weight then I don't see why the smaller setup (14/42 for example) isn't already in the cards.

I think there might be a problem with making a 415 front sprocket that small, but that would be a question for Mark. The best way to get a hold of him that I've found is to text him. His number is on the website.

A costly venture from Germany.

I'll search for an email.

Pm's are normally linked to email. U could try that.

Anyone using this 415 chain on their race prepped 300 ninja's?

Ok to do so , the few extra hp , will be ok? Or stick to 520?

[subxero]

not sure about people using them on 300 but from what I have read in many threads is if you race, make sure it is within rules, and if it is allowed then it can't hurt.

less weight, it's rotational so a little bit goes a long way and potentially less drag from a non o-ring chain.

Does it give you more HP, not necessarily but less drag of chain will allow you can get more of the hp you are producing to the ground where it matters, probably not physically noticeable, but if you run tight lap times you might see something.

In short, if you race and it's allowed why not give it a go, in a game where fractions of seconds can make a big difference any edge is a good edge IMO

We were racing our 300 last year with the stock gearing out at miller and we just put on the 415 kit with the stock ratio. Monday we go to the dyno to get it tuned from the winter Mods so i will have a number there but nothing to compare it too as we never dyno'd last year just put the Bazzaz Tuner on and went with that map. We will at least have the initial number before tuning to compare some numbers and we have our first track day saturday the 29th so I will get some feedback from the son on that and I may ride it also to see how it compares to last year as i rode it stock and then Modified as it was and then compare to now and give you some feedback but the 415 chain setup will definitely help with acceleration!

[IRich]

A little late but the initial dyno run was 34hp from last year on 88 non ethanol fuel and our new # we are at 41hp with the same fuel and the 415 kit and some better tuning than the auto tune we used initially.

I think some of the other 250 guys from the club will be ordering them some after they saw how freely the rear wheel turns without the extra weight of that 520 chain...

[subxero]

for a minute I thought you were talking about a 250 and I was ready to throw the BS flag

hows that 415 holding up with the reported 40+hp? whats the life expectancy? obviously you are running the kit, aluminum sprocket, and non - ring chain right?

[IRich]

Yes the aluminum non o-ring set-up,the chain is holding up well. the set has 2 trackdays on it and 2 race weekends on it and between the two I adjusted it a quarter turn so not much stretch yet and I take the chain off and clean it and resoak it in oil and then relube it. I don't know about stretch this time cause I drop a tooth in the rear but the chain seemed fine also. We are doing a school this Friday so the bike will be getting a lot more miles than a track day so we will see how much stretch. with the chain and new gearing the axle is in the middle of the adjustment. If racing I wouldn't hesitate to run it, I just need to get a spare for that one time
