Since you are in Canada and riding season is over, spend some money on books. First recommendation is Total Control.

JacRyann and ninjabraap have by far the most valuable input here.

From my experience, the bike in stock form was able to outperform both my physical and mental capabilities for over a year. This means the bike was able to maneuver faster than my body was capable of steering, with my arms, and mind.

It wasn't until I intentionally sought out the limits of the bike (by the laws of physics) knowingly and willfully crashing it in a closed course, that I realized what the 250R can do. Most specifically, u-turns >30mph, and almost nose bleed handling on extremely tight mountain roads. At the end of the day, the only question to answer is "Am I willing to risk death attempting to find the limit of this machine?"

Do note this is while in "stock form". The pics are in my photo albums and can be viewed by all ninjette.org members.

I hope to save your life OP with this sentence : Take the "journey" slowly and savor every day of it.

Finally, to exemplifly the mentality of upgrades, I will tell you the first upgrade I purchased was a 150 width rear tire. The concept was to eliminate the fear of rolling off the edge of the tire, as the 250R cannot mechanically/physically ride on the absolute edge of a 150 tire (youre on the fairings by then). Then it was rearsets to teach myself to lean that bike no matter what (to steer out of danger). You upgrade to teach yourself. Up to 90mph the bike WILL do more than you can tell it to. And at that speed, mistakes are...unforgiving

Live to ride again another day

After dealing with terrible customer services at cell phone providers here for years, I've discovered therapeutic use of yelling and cursing..

The best upgrade I did to my Ninja 250R was putting a set of Diablo Rosso II tyres on it. The bike felt stuck to the road after doing that. Those particular tyres don't seem to last too long though.

I'm actually using Michelin Pilot Street Radial tyres now. These last much longer than the Diablo's, but they don't feel as sticky/grippy. They're definitely more confidence inspiring than the stock tyres though.

Oh! Another thing I did which made a noticeable difference was upgrading to All Balls tapered roller steering bearings for the headset. Someone on this forum is in love with them and when I eventually needed my bearings replaced I could hear this guy in my head. I caved in and gave them a try. The steering did feel much better after doing so.

If I had to choose between fancy tyres and the bearings I'd definitely choose the fancy tyres.


If you're new to riding, make sure you get full protective gear before improving your bike. ATGATT and all that.

Planning on getting Power RS next season. Currently have stock shinko on front and pilot street radial on the rear (changed by the previous owner). Local shop recommended Power RS and I think it's cheaper than the Pirelli.
Will keep the bearings in mind. I checked the website and cost isn't too much.. might as well get em changed I guess.

THanks!

As a noob who is probably too excited about motorcycle in general (small dream of mine for long time so happy to see it materialize finally)
I been reading alot in different forums and watching too much youtube.. I don't want all that infos to fill my head with too much ideas. (Ex. being able to pass bigger bikes in corners one day.. haha)

I'm planning on doing small upgrades but wanted some opinions/suggestions from you guys.

Upgrade I will be installing: steel-braided front brake line (Galfer), R6 throttle tube mod

Already installed: EBC HH Sintered brakes, K&N Air Filter

Thinking about installing: Racetech front suspension springs and oil upgrade, tires (Michellin RS or something.. currently running on stock front and hockey puck for the rear), some sprocket tooth number changes in the future

I would like to make the bike to be more responsive and stable/fast around the corner. No tracking with this bike but mainly used as a fun toy / commuter. Not interested in exhaust or jetting.. unless adjusting current setting.. Hoping to turn it into a fun cornering machine that can double up as fun grocery run machine.

I'd appreciate any advice on the set up from you guys who have done it or have knowledge on the matter.. especially concerning the suspension set up. If changing out the springs and oil is good enough or should I be looking into GSX swap... if there's merit in going one route over another.. etc..
Get on this website's mailing list "motosport.com". Last spring they had a sale I took advantage of. Bought one Galfer braided steel line and got the second for free. It's basically a 1/2 half off sale. They may be doing it again. Moto Sport is basically a dirt bike retailer but I have purchased a few thing from them I couldn't get elsewhere.

Restrain the middle finger in the L.A. area. They just shoot you in response.

Unless you can work in a heated area you have every right to hold off. I've got a upper fairing that's pretty torn-up that I got for a song. It's split in two at the headlight plus some other stuff. I have a good start on it but I just finished repairing another upper fairing. These are just spares. The one on my Ninja is just fine. I hate doing body work because I'm too impatient. Instead I'm restoring a 1960 Johnson 3 H.P. outboard motor. I need a break from motorcycle stuff. Kick back, open a couple of brewskis and put on some tunes. It'll be warm again soon.

Yeah, it got to a balmy 42 degrees F here on 01/20 and I took a 30 mile ride. It was cold but fun. 46 days until the first day of spring! Dang!

update

weather isn't great but finally warm enough to get some work done on the bike.

Thought I'd start with the easiest and possibly the most anticipated upgrade (for me anyway)



R6 throttle tube upgrade! tube is not from Yamaha but Motion Pro brand.. bought for 12 bucks at local shop. Only mod needed was to cut the end cap off. Helps to have motorcycle DIY shop near my place.



Cables remounted and forgot about the hole on the bar.. but remembered after trying to fit the case back on and wondering why it's not closing/fitting properly..



How it looked last night. Had to ride to local motorcycle shop to buy a new grip like this in rain.. haha. Couldn't get the stock grip off the old tube.. figured I might as well get something new.

Most difficult part of the whole upgrade was getting the bar ends off. Thanks Red locktite.. good thing the shop had a heat gun.

Also for anyone else thinking about doing this upgrade, I'd say it's totally worth it. Not having to break my wrist trying to open up throttle is great.
I got a new grip on now but forgot to take pix.. I'll include later with more updates.

** local shop told me to use hair spray to get the new grip on the tube.. it may sound silly but that did the trick.. easy slip on with bit of force

El cheapo installed

Upgrade process has been slow but it's happening!


stock can about to be ripped out of the bike


As some members have mentioned in other el cheapo exhaust posts.. there is bit of gap in between and this lady who is restoring her sick 70s Ducati helped me with the installation (she pretty much installed herself for me.. ha). Using cut beer can as a shim


We ended up cutting a bigger piece of beer can so it extends beyond the tip of the pipe


fitment check with the spring. Those springs were PITA to install


worked out alrite


skipped out on 'Akropovic' sticker...


There is bit of leakage between the exhaust and the metal thing it comes with but nothing leaking at the part where we beer can shimmed. No biggie I guess.. if it gets worse, I'll just get it welded or something.

Sounds much better and kept the noise baffle thing in there. Next up is rejetting with dyno stage 2 kit and 40 pilot jets.

MOTM - Aug '15
If you're a bigger rider, upgraded front springs may help a lot. This thread has a chart for quick reference of what spring rate you should be looking for with various weights. Based on RaceTech's calculators, the front springs are only good for <100lb, while the rear is optimal for ~210lb. If one end is good for your weight, the other end probably isn't.

The EX500 has even softer fork springs, but I consider them the single best mod (out of $2000+ that I've spent) I've done on the bike. If they're too soft, they won't be able to absorb bumps well, and they'll be squishy when you're pushing it hard. Getting springs of the right rate will make it perform better and be more comfortable at the same time.

guys.. I appreciate the infos on front shocks/springs.. and I do have them on my list of to-do for the bike but I've reached the max budget for this year for bike mods and gears. (Bought some more riding gears for safety)

Married with a child that needs to be in daycare in Ontario, Canada is hard on my wallet. Around 1300 per month for daycare... and we just voted for a guy who ran on bringing back 1dollar beer as his political campaign over the other party that offered free daycare.

Also, recommended that I do both front and rear to match the stiffness?

on the bright side.. my goal for the second year of riding is to drag knee.. and I've recently touched knee on the ground but also touched the peg feeler.. gotta work on body positioning I guess..
Hopefully I'll have some bike mods to update with you guys over the weekend! dynojet stage 2 kit has been sitting on my shelf for too long.

The rear suspension on new-gen is much improved over last generation due to some changes:

1. shock with stiffer spring and damping along with preload-adjustment

2. revised leverage-ratios with knuckle!!! This alone probably accounts for 80% of improvements. New knuckle moves shock more for same amount of wheel-travel. This increases leverage shock has on swingarm and same shock would have stronger "push" on swingarm.

When I upgraded my pre-gen to new-gen rear-suspension with entire swingarm assembly, for giggles, I re-installed original pre-gen shock. Wow, it actually worked better!!! So rear-end on new-gen bikes don't need as much upgrading as fork.

For fork-springs, other brands like Progressive or Bitubo can be had for less on eBay. No-cost option is to cut off 4" of spring and replace with PVC spacer. Back in '80s, when aftermarket products wasn't as abundant, this was pretty standard procedure.

Does the PVC mod actually help? without changing the stock spring.. wouldn't it be just as squishy as before? I've heard of this before but wasn't too sure if it actually worked

Yes, it does work because spring-stiffness is based upon number of coils. The more coils you have, the softer the spring (because each coil defects same amount given any load).. By removing some coils, you stiffen the spring. Usually removing 100mm is good amount on these bikes. Then adjust pre-load by using 105mm or 110mm PVC spacer.

You can actually calculate how much to cut off the spring to give a desired rate.

new spring length * new spring rate = original spring length * original spring rate

If the stock spring is 450mm long (that's just an example - don't actually use that number) and 0.65kg/mm, that gives you a total value of 292.5 for the stock spring. If you want it to be 0.75kg/mm, you just divide by that and get a new length of 390mm. For 0.85kg/mm, you'd end up with 344.1mm. If you want to get really precise and go for 0.7945kg/mm, cut it down to 368.16mm.

The only downsides to cutting springs are that it's a permanent mod, and if you're really heavy, you may not be able to shorten it enough without interfering with operation of the spring (obviously you can only cut off so much length before it doesn't work in the fork).

You'll need spacers to make up for the removed length of spring. The "extra" length of spacer in the fork tube (in either stock or modified form) is what creates preload. That's probably not the correct setting from the factory, and it will necessarily change when you change the spring rate. You'll probably have to tweak the length of your spacer to get the correct preload/sag setting. ProTip: It's easier to trim off a little than it is to add a little back - start longer and shorten it.

If you have the preload properly set on the stock spring, you can compare the total length of the spring & spacer to the total length of the fork's spring chamber to figure out how much force it's applying on the spring. You can then use that to adjust your spacer length to give the same force on the new spring's rate.
