I've looked at a fair number of "best mods" threads but I notice all of them seem to be about offroad performance (Mostly) but seeing as I ride about 98% onroad I would be interested in seeing what you tarmac guys like the most.
I am doing a "as I get the money" kind of slow build on my '12 KLXs to make it a fun commuter/weekend blast kinda bike so here is the list of mods I am thinking,
~FMF powercore 4 (already have that),powerbomb header and dynojet stage 2.
~some kind of street tire probably 80/20 onroad offroad.
~BB 351 big bore kit for wheelies
~A sprocket selection from 13T to 15T
~Sliders and handguards for all the crashing I really hope not to do
so what have you guys done to your bikes to make them a little more road fun/friendly? and what do you think of the mods outlined?
Thanks,
Hunterman.

 

You have most of it covered. Add a 20 dollar Uni air filter and it will really liven up and give you crisp throttle response. Toss the snorkel and drill some holes in the air box lid.
I ran Bridgestone Battle Axe ( or Battlewing, cannot remember) which were rated for 90% on road and 10% off road tires. They were great on road before I did the Motard conversion.
Stiffer fork springs are a must for on road as well, to get rid of the dive when braking hard.

 

If your doing mainly street, I'd recommend a K&N air filter with the KDX snorkel. I have 70/30 tires which are great for daily street riding but with enough tread for fire roads and trails.

 

Why do you say K&N over Uni? the reason I ask is because I can order a Uni within the country but have yet to find a K&N.
Thanks,
Hunterman.

 

Uni is better for offroad, k&n is better where there isn't any dust.

 

If I was gonna do alot of street riding:
#1 New Seat
#2 Bigger tank.

 

Different bike.

If it wasn't for the needed off-road prowess, there are tons of bikes that are better on the road.

I ride mostly on-road but bought the bike for my enduro, desert race, and poker run fetishes. So the most great thing that applies to both is the vapor computer. It is accurate so you actually know your speed and distance. When I commute it isn't important but for long road rides I find the tank ridiculously small. I can't ride more than a couple of hours without the damn tank running out of gas.

 

Definitely agree with some of this. The KLX borders on just about sucking on pavement. In one respect it will do it better than a similarly sized plated race bike for sure, but I guess I've owned enough road bikes that it's almost depressing to have to ride this bike for very long on the highway. In really tight, urban traffic it's not too bad, but this engine is not a good choice for spirited pavement for my taste...even the SF. The Yamaha WRX kills the KLX-SF in the small street bike category. And if you go to the 250/300 Ninja category, the KLX isn't even in the same galaxy.

You guys know I love my KLX, and I put it through its paces fairly decently in off road situations. But when this bike is on pavement for any real distance, it just gets ridiculously boring to me...and I don't think there's a lot that can be done to bring it to any level of inspiring street performance. This is the argument for having two bikes.

 

That's why you go supermoto!!!!!!!!! I wish they made a klx450sf

 

It more fun to ride a slow bike fast and can get a "klx450sf" here in Aus. or even the older "klx650sf"
