Sooo I wrecked my bike...gear saves

Only took a month and a half 😛

picked up a Ninja 250 and been getting the hang of it. Been averaging over 2 hours a day riding and about 1,500 miles in the 45 days or so I've ridden it.

Been having trouble shifting the past few days. Down shifts were mostly fine, but was missing upshifts. Oil was changed a couple of weeks ago, chain was in spec. It was due for full service and was going to take it in next week or so for that. All day yesterday I was fighting upshifts and even came home to change boots mid day to see wtf my problem was.

Conditions were about 630pm, 90 degrees and partly cloudy, unlimited visibility. Two 90 degree bends, first to the right, next to the left. Approached bend one, let off throttle applied brakes and downshifted, entered corner and applied throttle at exit. Next turn, approach, roll off throttle, apply brakes, downshift and couldn't get it in gear. Apply more brakes and still nothing on the downshift.

At the oh shit moment applied full rear brake and leaned hard left but didn't have any power. Bike hit left handlebar down and I fell on my left side as the road ended. I estimate the speed to be 10-12mph. Bike landed on top of my left foot which I slid out from under and impacted on left shoulder, left hand and hip and rolled onto my back. Helmet never touched the ground (was a slight downward slope). Probably slid 8-10 feet from where the bike stopped on gravel and then onto grass (yay).

Knee was road rashed but got to the bike and uprighted it no problem. Shook my head and wanted to asskick myself.

Damage to bike? Left blinker popped off. Will easily be able to reattach it.

I was wearing a:
Bell RS-1 (never touched the ground)

Rev'it! Sand Pro gloves. Left glove hit first but is fine, wasn't on it long.

Jeans (boooo!. Road rash on my hip and knee, no real pain, a 2/10 on damage. Decided not to wear my riding pants with armor today...won't do that again).

Boots (some hard ass, thick sturdy boots I got a while back. The sole took the impact of the bike.

And the star of the show: Dainese mesh jacket with Forcefield back insert.

After I was done sliding, the pain on my kneecap was obvious. Rode home, still fighting with the transmission trying to get it in gear the entire time. Kept missing shifts. It wasn't until I got home and checking things over that I remembered ending up on my back. Jacket had a ton of debris and dust on the shoulder and back and I couldn't even feel that I'd hit back there.

I wiped the jacket down and there isn't a mark on it except for some stray dirt and trash. Shoulder, side and back that were obviously slid on worked perfect. Couldn't be happier with how the jacket did.

I'm not blaming the bike, it was 100% my fault. I got fixated on trying to downshift and fighting the bike rather than pay enough attention to running out of road. I'm in my 30s and an accountant. I wasn't showing off or riding beyond my skill; just made an inexperienced mistake.

I'll admit I've been riding beyond my skill level, but was in full, beefier gear and fully focused and expecting everything. This was just an afternoon jaunt, tooling around with no aggressive riding.

Moral of the story? The only part of me hurt was the part not wearing proper gear. And not hauling ass around tight corners and being parallel to the ground, but at 10mph in an easy curve.
 
Not sure what caused the gear changing issue... or the accident quite frankly. If you're moving it is generally pretty easy to select a gear. Every once in a great while I'll shift into neutral instead of 2nd on an upshift if I do a weak assed gear change but can't remember the last time I couldn't select a gear while downshifting.

Glad you're okay though. :thumbsup:

For others researching riding gear . . .

Diamond Gusset Defender riding jeans.

$10 Bracken knee pads from Lowe's garden department . . might ACTUALLY wear these for those nearby errand trips. Vega boots.

At least you did a low side. Everyone dumps their first bike at some point. At least yours was minor. Glad you are okay.
 
Seems odd that you couldn't get it into gear. Have you gotten it looked at since? Every now and then I miss a shift because I don't pull up hard enough with my boot, but generally speaking shifting is always fine. Could just be some noobie mistakes you're making.

Glad you're not an idiot though and you wear your gear...

That isn't the moral I take away here, but I'm glad you're mostly ok.
 
I'm no biker but everybody falls at some point I assume, so it's good you didn't destroy anything. I also heard that wearing jeans when riding a bike is superstupid and should not be done.
 
I am still trying to wrap my head around how missing a shift caused this crash.
It sounds like you panicked and dumped it?
 
Wouldn't it be just as valid to ask if he'd recently had peanut butter?


It's extremely valid.

We often have debates as to whether or not a 250/500 is too small, complete with numerous members who insist it makes no difference and people should start on 600 supersports.

Part of what keeps a motorcycle planted in a corner is 'powering' through it. If you loose power mid turn it's extremely unnerving, and difficult to keep the bike leaned over and turning, aside the fact that it upsets the suspension.

I've spit a chain mid corner and very nearly ended up in a ditch over it.

Some of that. Some just the mechanics of how bikes work. Power will stand you back up coming out of a turn. An experienced rider probably would have been fine, but newbies don't have the right reflexes yet. I know I've missed a shift mid turn and not dumped it, but it does upset the bike and is distracting.

As for bike size, it just magnifies all mistakes like this.

Actually what stands the bike is up is LACK of power... Try it... Go around a corner fairly quickly and carefully let off the throttle... The bike will try VERY hard to push itself upright.


In my close call it look literally everything I had to keep the bike leaned over... I already had my knee skipping along the ground when the chain broke, and I was hanging off like a crazy monkey trying to stay leaned over.

Hmmm not what I was taught, but I won't say I'm a guru on motorcycle mechanics.

It's due for factory service and I'm not experienced in working on small engines so was going to let a bike shop (not a dealer) work on it. I have spec sheets on recommended timings and adjustments and going to have him match or see how close they are.

I've done some reading on the transmission issue and doesn't seem like a completely foreign problem. Neutral finder problem, or a linkage issue if the shifter is not held until the clutch is let out. I'll leave it for the shop to diagnose.

Again, it's not the transmission's fault, but my fixation on trying to downshift and failure to maintain speed.

As noted by others, applying power in the turn helps keep it planted. I didn't have it and didn't have the experience to compensate for it.

And doubt I would have been going any faster on a bigger bike, but the issues would have been a heavier hit on my foot, harder to pick up and more costly possible damage (I'd assume). However it would be far easier to get out of control hitting a pothole or something that could cause you to slip on the throttle and go into orbit.

Is it not engine braking on the rear wheel producing that effect?
