cameronjones239,
What is the weight of your bike? Mine was 285 lb last time I weighed it. Since then I've installed a dry break and removed some other stuff so I think it's about the same now. Maybe a little more because I had to get a heavy a$$ 520 oring chain from a local dealership in a pinch right before a race weekend, |

285 is killer for a 300! I've heard a rumor of a guy with a 278lbs bike but no idea who and closest to that was I think 295. I currently have 2 Ninja 300's, one is a superbike build with some spears goodies. The other is going to be a supersport build to hop in with CCS for next year. Currently torn down almost to the frame as I prepare it to get the works. Hopefully in the realm of where yours is once said and done. I hadn't messed with weight reduction all year on my superbike build, last week I finally removed a lot of misc plastics and brackets. When I weighed it in the spring she was a fat pig at 331lbs with roughly 1/3-1/2 tank of gas. Can't remember if my lap timer/gopros were on or not. I plan to weigh it before my race this weekend at Hastings with track addix so I'll have an updated figure soon. I should note the lightweight wheels were a customers that he let me get the weight off of. Hopefully I can pick up a set soon though |

Ha will do, I'm looking forward to it. I finally got to race with Drew J at heartland park a few weeks back. Had an awesome battle for about 5 laps and it was quite a dead lock. I tried to force a pass inside a lapper to separate us, couldn't make it work, checked up, rear ended by 2nd place and lappers rear wheel won the fight vs my front. Nowhere to go and basically highsided off the bike.

There's a pretty good chance I'll be running Moto3 sized slicks next year. I just scored five brand new sets for free. The catch is that they are 5 years old. Shouldn't be a big deal since they were stored properly.
Should be another weight savings. I'll have to weigh them when I get them. That might precipitate a switch to RS125 or TZ125 wheels. |

If I were doing sprints only, I'd be installing a two gallon plastic tank in place of the steel tank. I did this on another project racebike by using an atv tank I bought off ebay.

The things that added weight this year: Went to a 4" wheel from a Ninja 300 to accomodate the width of the A-13 rear. About a three pound weight gain when combined with the bigger tire. Installed a dry break valve on the gas tank. Maybe a half pound gain because I removed the filler neck from the tank to install the valve. Put a heavy-assed 520 o-ring chain from the local dealership cause I was in a pinch right before the first race weekend. Probably gained two pounds from that. 278 lbs is very doable. As I mentioned, replacing the fairing would save 3 or 4 pounds, going to a nice light 520 non o-ring chain would save a couple more, and nice light wheels (maybe from an RS or TZ 125) would easily take care of the several more pounds. All this weight savings makes a big difference. Considering that a stock 250 Ninja is around 345lb without gas, the 56 or so pound weight savings on my bike is fairly significant. Leaving alone the difference in acceleration on a 30hp bike, strap an extra 60 lbs on any bike that's not a Harley and most people would notice a big difference in handling. The best evidence is the several people say that we've been going pretty fast on that 300 Ninja. Then I tell them it's a 250. ![]() |

Wikipedia showing the ninja 300 weighing in at 362 dry and 385 wet, not sure how accurate that is but it sounds close. I'll have the weight for both of mine tomorrow. We're finishing them up today. We found a pound cutting off the kickstand from the frame, another almost pound off the steering lock. Another 8oz cutting off just the lower half of the front stay, still need to cut the tabs off of it though.
If I remember right a 415 chain and sprocket kit weighs less than just the 520 factory chain alone. I'll have weight of a 415 134link today and get some other parts of the list updated.

I cut off the part of the subframe that would support a passenger. Saved about 4 pounds there. Also the exhaust/passenger footpeg bracket. I removed most of the middle and just left enough meat around the threaded holes for bolting the exhaust bracket to it. The sprocket carrier is way, way overbuilt. I'll have to figure out some way to make it lighter if I don't go aftermarket with the wheels. |

Good to reduce your reciprocating mass and unsprung weight as much as possible. I think the Bridgestone evo S21's are one of the lightest tyres too.

Design is a big factor here as well. You don't want to match 1:1 the shape of steel sprocket in aluminium as 1/3rd weight may not be enough. You'll want to have more material, even mostly solid aluminium sprocket for only 1/2 weight savings. That should be sufficient strength. In end, it's the teeth that will wear out faster and require more frequent inspection and replacement.
On my street bike, I use a lightweight steel 520 sprocket that's actually close to aluminium in weight-savings. I get about 1.5-years out of my 428 alloy rear-sprocket on my race bike with flipping it. I do like the 428 conversion though as the chain lasts longer than factory 520. And I can fine-tune final-drive ratios in smaller increments using 18/57t, 18/58t or 18/59t depending upon the track. Last futzed with by DannoXYZ; October 18th, 2017 at 11:32 AM. |

You can add these to your rim weights:
GaleSpeed Type-GP1S Rims: Front 300-17 (28870071) = 3.143kg Rear 400-17 (28870171) = 5.086kg with 40T steel sprocket

I think Renthal hard anodizes their aluminum sprockets for better wear. I've seen Vortex aluminum sprockets sheer teeth from too much power (and probably too much wear at the same time), but for smaller bikes I don't think you'd have any issues.
Steel would definitely wear longer. That steel RS8R sprocket is really opened up. It would be interesting to compare the weight to something like a Vortex aluminum one. |

Clearly the steel sprocket that you show has been more optimized for weight reduction than either the stock sprocket or the aluminum one, so the weights aren't reflective of what is possible with a good design in aluminum. One thing that you cant get away from with a steel sprocket: The mass concentrated at the perimeter where the teeth are is going to be higher than than for aluminum. That means the moment of inertia (MOI) is going to be higher and a high moment of inertia affects acceleration. Think of swinging a baseball on the end of a rope in a circle. The longer the rope, the higher the MOI and the harder it is to swing the baseball around. Still the steel sprocket that you show looks like a fairly good design and certainly you should get more life out of it than an aluminum one, but it's a compromise that is your choice to make It's going to cost more for the well-designed part and have a higher MOI. I often find the aluminum sprockets I want for less than $30.00 on ebay which is likely less than half the cost of the steel one. I'm willing to sacrifice the time it takes to swap out the to a new aluminum sprocket when it wears out faster. (not that often on a 250 Ninja) IMO hard anodizing doesn't do much, it is very thin and it's effectiveness is also dependent on the strength of the base metal it is applied to. And all aluminum is not created equal. If you really want a good aluminum sprocket, then get one made out of 7075 aluminum instead of the more typical 6061 stuff. 7075 is significantly stronger, allowing further possible weight reduction with careful design. We're not likely to shear teeth with 250 and 300 Ninjas, but on one of my other bikes I have seen what seems to be quicker wear on Vortex sprockets than other brands. |

I'm an aluminium fan as long as the application is right. In my case we were talking 30.4 HP on a standard CBR300 for hard sports riding duties and the odd track day in a novice class.
So even I was surprised how much mileage I got out of it. Also, there are different grades of aluminium and like a lot of things in life, it seems to be a case of you get what you pay for. I forked out $50 for mine from PMP sprockets in Texas. They offer a hard coat option as well for another $14. Probably a good option for racers but i didnt go with it and still got 25,000km out of a standard one. Very happy with both the product and the service.

While 7000-series may have twice strength and fatigue-resistance as more common 6061-T6, so you can make it lighter in the stronger alloy. However wear-resistance is same for both. Same rockwell, same density, same modulus, etc. Even hard-anodizing isn't enough to extend wear much, you'd need something like a DLC or ion-impregnated surface.
I think ultimate sprocket for weight-savings AND strength/durability would be an aluminium centre carrier with steel outer-ring for teeth. Kinda like floating disc-brakes with separate centre. |

DLC is pretty cool. I've used it in some applications for work. The problem with aluminum as a substrate is that it moves too much underneath the DLC which would cause it to flake off fairly quickly. DLC on steel would last longer. They already have what you're talking about so you may want to check these guys out: https://www.supersproxusa.com/ I ran an entire season of endurance racing with one aluminum sprocket and it's still good. I can deal with that for the 25 or 30 bucks it cost me. I don't get cheap quality sprockets. I'm just willing to take the time to cross-reference them to find the deals on ebay. |

Looks like JT486 alloy sprocket fits. Supposedly same as EX500 and used for 520-conversions of GSXR-600/1000 and R1/R6 bikes.
Any experience with this? Not bad pricing either. |
