Default Just bought my 48 and love it! However... (Expected Much More Power)

I'm a bit disappointed as I expected much more power. I didn't buy the sporty for racing or whatever but I'm coming from a Ninja 650 parallel twin and although I did not test ride the XL, I compared the stats on paper.
The XL has (on paper at least) 96nm / 70ft-lb of torque versus the 66nm / 49ft-lb of the Kawa. You'd think it's a no-brainer that the XL would pull like a beast... but it doesn't.

I'm glad that my friend convinced me to take the 1200 instead of the 883 as it has "loads more power" than the 883. Thank goodness I didn't take the Iron - if the 1200 has loads more then the 883 must be a dead fish. But here's the thing I'm pondering about. Did HD on purpose make the stock bikes underpowered? I'm reading on how the AC and pipes and EFI remapping improve the bikes so much more than stock, but does it really? Will I just waste my money by getting $2000 of performance parts?

Sorry for the rambling, and cheers from Australia,
TonyPolony

This is THE BEST Sportster Resource!

Please put at least your Country in the LOCATION FIELD of your profile so we can better help you when you need it... (the STATE FIELD does not show on posts)

Then post a PICTURE of your ride... (Host it offsite, get the link, insert it in your post by clicking icon: )

Power is a relative thing - Sportsters aren't Sport Bikes per se ... but if you spend some money to get past the 'introductory configuration' from the factory, you can find a lot of power lurking there...

Welcome. Trying to compare the feel of a stock Sportster to the feel of a Ninja 650 is futility- totally different animals with totally different behaviors.

And yes- Stage 1 will noticeably increase the power, and if you scrounge a bit I'll bet you can do it for less than $2k.

I hope you at least like the new bike, perception of power aside?

Better take the 2000$, buy a used parallel twin 650 kawa ninja and please your thirst for speed.
HP for HP, the ninja have the same power as the sportster, just shave 300 lbs out of your 48.
What you should have done is buy a 5000$ sportster then make it a 90 inchers. Only way to beat a 650 metric bike.

Welcome to the forum, and congrats on the new bike!

The stock exhausts and air cleaners on these bikes really choke the motors. Change those two things, and add a proper EFI tuner device to get the fueling right again, and it really wakes the bike up.

However, be aware that many of the exhaust systems on the market, and even some of the air cleaners, are not really performance pieces. Looks and sound are generally bigger factors in the design of these things than performance. So choose carefully, and basically ignore manufacturer claims of power gains, 99% of it is BS. Separating out the pieces that are truly designed for performance is the hard part of this exercise.

We've done a fair bit of performance testing on exhausts, and you can see those results here: http://www.hammerperf.com/ttxlexhaust.shtml . Interestingly, there's really no correlation between price and performance - in fact one of the worst performing pipes we've ever tested is ungodly expensive, and the best performing pipe we've ever tested is downright cheap.

We haven't done the equivalent level of testing on air cleaners, but we wouldn't exactly be unbiased, because we're in that business.

Don't cheap out on the tuner. Get a good flash tuner, preferably one that's user friendly and has autotune capabilities. We like and offer and support the Powervision from Dynojet.

Stock EFI 1200's make 60-65hp at the back wheel. With a well chosen pipe, air cleaner, and EFI tuner, that number can be north of 80 ...



This result came from a 1200 equipped with a Patriot Defender exhaust, Air Hammer air cleaner, and Dynojet Powervision tuner. Heads, cams, pistons, etc are all stock.

Those three pieces - a Patriot Defender, Air Hammer air cleaner, and Dynojet Powervision tuner - can be had for a total of under $1100.

Moving up the power scale from there, you can do cams and/or engine kit and/or head work. We have a tech article that shows the logical progression and what to expect here: http://www.hammerperf.com/tthoppingup1200.shtml#04+ . North of 120hp is possible if you do all three.

Be aware that a throttle body swap, as suggested by HD at power levels below 100, has proven to be a terrible investment in our testing. See the testing here: http://www.hammerperf.com/ttxlthrottlebody.shtml . It really doesn't make sense until you're crossing 120hp. It's a massive waste of money below that level.

Any questions at all, feel free to shoot me a note.

I'm pretty disappointed with the power of my 72 also. My KX125 was faster than this thing. Oh well, now I know I need a 110" next time!
