You probably saw my other post about the caliper, but I got the 15. Currently using with stock caliper, and it is a bit wooden. It works great with stock caliper if you've got a nice pad and rotor set. Steel lines as well.
The 15RCS is designed to work with their aftermarket 4 piston caliper, and the 14RCS is the bolt on upgrade.
Depends what caliper you want to run with. The stock caliper isn't bad, I've seen many club racers use stock 300 calipers up front. That with the 14RCS is a great rad combo with a lot of potential.
But if you don't have ABS and want the absolute premium in brake power for these single rotor machines, 15RCS and the Brembo 4-piston caliper would be end game brakes.
That said, I like my 15 enough with stock caliper that I won't go buy the 14, since I found my magical pad set match. Standard HH pads from Galfer or EBC I kept blowing up on track and they felt bad. The EBC EPFA half track half street pad is the only pad set I've found to work with the 15RCS and stock caliper that provides the best feel, actual stopping power, and never overheats. I am hard and late on my brakes, so this setup works great for me. Just a bit hard on the lever pull, but it has taught me a lot and prevents me from locking the front ever.
Here is the EBC HH pads I blew up. I broke them in and rode them around for a good amount of street, then 2-3 sessions of track in they rainbow'd and shattered, and squealed insanely loud in the pits. Never again. EBC HH pads aren't bad, but they just absolutely did not work for my setup and style on track. Nothing was wrong with my calipers either, I rebuild them often.
Sorry for the ramble, hope this helps.

Damn you cooked those pads! I did know that you were running the 15 with stock caliper. Do you think the 14 would give me better feel than the 15 with the upgraded caliper? I’d rather better feel and less stopping power than less feel with more power….
I guess my real question is, will the 14 have enough power? I'm thinking it should work well since there are many people that use the tokico caliper with the stock master and say it works well. The 14 is still a step up from 12.7 so should be (in my thinking) better than the stock master but not too big as to lose much feel? What a rabbit hole lol...

Hmm, that's a tough call. I am almost certain the Tokico is still much larger piston areas than that of the stock caliper, so if you've got that, I would do the 15. It will be a match made in heaven. I bet the Tokico 4-piston is similar in fluid dimensions to the Brembo 4-piston caliper.
Do the 15. Heck, if you actually decide on doing the 14 in the end and it's too soft for you, I will personally trade you my 15 for your 14 if you hate it! Serious offer. Think about it!

Damn, looks like I’m getting the 14 then lol! I honestly think it will be more than fine. Prob they both work well just a matter of preference. I think Gregg is looking at it from a racing perspective where I am just looking to get premium brake feel. To tell you the truth, I never thought the stock front brake was bad haha. I’m sure with new pads, rotor a fresh rebuilt caliper and Brembo master it’ll feel like butter.
I did some checking and the Brembo caliper has the exact same size pistons as the Tokico, 30mm and 34mm so I’m sure the 15 would work as well. I’ll save a few bucks and get the Rcs-14 bundle and let you know how it works.

Sorry Sparky, I ended up getting the 15. I think it was the way to go with my caliper like you said. I emailed both Spears and Norton Motorsports and they all said the same thing. They think the 14 would work fine but the 15 is the better choice for a 4 piston caliper.
Have you thought about slapping one of these tokico's on your bike? It'd be cheaper than switching masters again. I have a spare set of seals you could have.

Right on man, good choice with the 15.
If I was going to do the caliper swap, I am spoiled by the Brembo M4 monoblocks I got on my GSX-R, so I'd probably get the Brembo 4-piston from Spears if I did it. I am just worried it would ruin the ABS functionality with the different caliper size. If I made the caliper too much larger, the ABS pump wouldn't be able to fully disengage the brake if I lock the wheel. So I am a little spooked.
I have been sitting on the idea of doing a full track conversion on my 300. It's had a full life, lots of miles, and it's modern enough that sitting every winter won't clog it up or anything... Maybe it's time it retired to the track paddock. Great bike I'd let any of my local riding friends use on track, and it would be absolutely killer for rain track days with full rain tires. ABS would be great for rain track days too.
Ahhh... choices. Would be kinda cool to not have to do insurance payments and all that jazz, but would also be rad for friends visiting from out of town to have a bike to borrow.
Caliper probably isn't in my future then. Lol.

I hear you on that. The Ninja would make an awesome track back for sure! I wish we had tracks out here near me because I would go as much as possible just to have fun and improve my riding skills. I was just reading you thread where you explained all of your Gsxr brake upgrades and I thought "I bet that wasn't cheap"!
I'll be like you this summer when I end up buying my buddies Vfr750. I'll have to pick and choose where my money goes and I'll bet it'll go towards the Honda. It'll need a complete going through, maintenance and I'm sure I can find a way to upgrade it.😁

Ah man a VFR750 sounds super rad! Indeed, keep us posted in the rando bikes area.
Yeah, my GSX-R setup was not cheap. In fact I am quite sure I spent far away the most money on the front brake system alone. Bad brakes ruin a motorcycle for me, and I tried to see what parts were still going to work for me, and in the end, none of the stock/included brake components were going to do it. Those brakes are life changing. That's what had me thinking about my 300 brakes, but alas, I think what it has is great for what I do with the bike and it runs on track quite nice.
I had a choice of where the money would go, and it went to front brakes first. Then suspension, then tires. If you got all good of those things, you really can't have a bad time. I am SO READY for track season, I have been reviewing all my old footage and I'm getting a laminated poster of my favorite track to plan my strategies.

Hello! Do either of you have specific part numbers/vendors to purchase either the brembo or the tokico? I want to do the 15 with either for my track only 300….I am getting ready for all the off season upgrades and thought that might be the way to go.
For the Brembo (RCS-15 is the part number as it is a universal master that will fit just about any bike) you can check HardRacing. Spears Racing sells them too but their prices are higher than other sellers. I'd just find the cheapest deal you can. The Tokico, you'll have to find used someplace like ebay and it'll likely need a rebuild, and get the bracket from SV Racing Parts.
Did you mean Brembo caliper? Spears is the only place I know of that sells the Brembo caliper complete with the bracket to fit the Ninja 300...

For the Tokico you can get any year SV1000, or a 2001-2003 Gsxr600 front caliper. If you get a Gsxr600 front caliper and it needs a rebuild, do yourself a favor and buy an SV1000 rebuild kit. They use the same seals, are about $10 cheaper for some reason and the All Balls kit I bought for the Gsxr600 caliper came with the wrong brake pad pins.

I have to correct my previous post. Spears is NOT the only place to buy a Brembo caliper and bracket to fit the Ninja 300. Get that stuff a lot cheaper see below!
Check out Carpimoto website. They have Brembo calipers on there for $115 and then all you’ll need is an SSR Brembo caliper bracket off eBay for $100. I can find the links for you when I have time later.
I ordered mine from carpimoto and even though it ships from italy, I got it in 4 days.
