Anyone here run there bikes with no hugger? How much of a mess does it make? I was looking at getting a chain guard with no hugger but wasent sure how much crap the tire throws up with out one.

I know that my chain throws crap even with the hugger/chain guard on. I can't imagine running without one. I wipe my chain dry after a thorough lubing with PJ1 Blue Label so I don't know why it flings so bad.
I was just wondering the same thing. Or just cutting the hugger off and just using the chain guard. I looked for after market options but didn't come up with much.
I'm also contemplating running no front fender also. I see alot of bikes on customfighters without front fenders. So it can't be all that bad.
I like the look of the naked wheels, but they both may be necessities for a commuter. A show bike that gets ridden to and from events probly could make due.
It's actually an aerodynamic enhancement device as well.
In terms of drag created by the air seeing the spinning tire.
To relate this to a car, think of the wheel covers used on a Salt Flats car so the side of the wheel is flush, with no deep centre recess. Similar concept.

Haha, yeah right. That's gonna make a difference on a 120 mph bike.

I am now laughing

mcromo44 is right at 80mph+ there is sufficient drag on your tire from the wind, a rear hugger helps. people pay extra to put one of these on there bike. a salt flat car is at the far end of the spectrum but is a good example

But I still want to laugh. I think that I wouldn't have noticed a bit when I ran my Kwak up to a calibrated 151(and felt that was as fast as I EVER needed to go) if I hadn't had my hugger on. Plus, I didn't notice a thing when I stuck a hugger on both my Superhawk and 929RR, well, except................for..................some .................................................. ......................mysterious SALT RESIDUE!!!!!!!

Across the pond the old Hornet 600 had no hugger & everyone clamored to get one on. The 919 comes with one & you want to remove it? I'd leave it...I've had enough "change".
I took mine off. It was ugly and i felt the "chain guard" offered little protection to warrent it. I've not been battered with crap from the tire nor had any inclination to put it back on.
Haha, yeah right. That's gonna make a difference on a 120 mph bike.
If you mean a 919 is a 120 bike, then you must mean a really sick 919
138 mph @ 3500 ft altitude
sea level test go from 140 to 143
aerodynamic drag agrees with dyno hp result to support above speeds also
a rear hugger would be starting to work at 120 and be of effect at 140

No, I mean a real world 919, not one that's been dyno'd showing it will run 140-143 with aerodynamic drag factored in. I live at sea level, and I'm here to tell you that there is no way in hell a 919 runs 140.
Plus, that rear hugger is really going to make a difference on an unfaired bike. Sure.
I personally ride my bike everyday without the hugger and chain guard, I did cut the piece off that holds the brake line in place. But I like the way it looks and there is no ungodly mess.
Also, are you guys seriously debating the aerodynamics of a 919 at 140 mph... First off, exactly how often do you reach that speed, and then after that I think the tire hugger is just about the least of your worries, how about the front end that has a drag coefficient of a freaking mack truck.
I took the hugger off my bike and was considering replacing it with a carbon fiber one but don't really feel like it is necessary now. After the initial ride without it I was a little concerned because a significant amount of lube/grit/other stuff was all over my pipes and undertray. I don't ride in the rain and keep my chain wiped off as much as possible and haven't had any problems since. I don't ride my bike at 140 mph and really just enjoy the way it looks much better. I definitely haven't noticed an aerodynamics or performance difference and I'm nearly certain the average rider wouldn't and possibly the only way you would notice is through wind tunnel testing. Regardless, I'm not putting the stock hugger back on because I only ride for fun and don't commute/tour. I think it depends on where you ride and how often if the hugger is really necessary. If I were commuting or touring I would definitely use it but since I only use this as a hooligan play bike its not as important to me.

My hugger is on as part of the "anti wet" strategy when rain riding with my spouse on the back, same reason the factory tailsection mounted "fender" is still on. The hugger makes an aero difference in the sense that it does, how much /, who knows and who cares. It's just the fact that it is an aero device in its own right, which I think is interesting to know.
As for overall aero on a 919 or any truly naked bike, laying flat with butt back on the bike so the back is flat, is a long proven aero improver for an unfaired bike. Do it, and a 919 can crack 140 at sea level - as long as it's geared properly and you have lots of room to let it creep up for that last MPH. My tacho is proofed, and working that back using ratios and tire size I'm touching 138 MPH @ 3500 ft altitude (Yosh TRS with PC3 and custom map and 2 more teeth on rear). Known CdA values from aero tests in the 70s and 80s in association with 919 hp also supports such speeds.
Naked UJM Bikes weighing the same and with not much more than half the power of a 919 were doing 120 40 years ago.
im not saying your going to get leaps and bounds out of it but it does help. just like the wing on the back of a car no one really ever drives fast enough to need one, but its there when you do. and its more of that street bike look anyways.
138!! 140!!! now i weight 160lbs. ive got my bike close if not to 150 (i know the tach on these bikes are off by 5mph so i factored that in) still putting my bike back together and i will find out for sure after that.(i have a power commander, baffleoctomy, flapper mod and ca emissions is off)
You can't actually turn Ca emissions off. You can remove the evap canister and install a powercommander, but the California bikes have different intake manifold (according to the parts fiche anyway). Just what I read. YMMV.

The Tach is off a little, but the speedo is off a lot...about 8%. That means it isn't a set speed it is off through it's range. At 50 MPH, it is off (reading high) by approximately 4 MPH, So when it reads 50, you are really going 46. That 8% inaccuracy makes it read off by 8 MPH at 100 so you are really only going 92. If your speedo touched 150, and you have nothing correcting the error, you are really only going around 138.
This has been beat to death in previous threads. I'm pretty sure the GPS verified top speed of a 919 is right around 144. If I remember correctly, it took a LONG time to make the climb from just over 120 to the top.
My neighbor told us the other day that when his Fat Boy gets to 165mph he starts getting kinda scared! I told him the only way for the Bob to go 165mph was if you shoved it out of an airplane about 2 miles high!
Man, he got mad, and didn't think it was funny!

"One would think that the Secret Service was smart enough to get serviced secretly."
I covered my naked body in vaseline to reduce drag and headed out to the airstrip. Ensuring I had a tail wind I rung the bike out to redline in all gears and the end result was 185mph.
I was running fully synthetic dino oil.
Tyre pressures: front 55 psi, rear 62 psi
Suspension - full hard at both ends and a free Ohlins sticker on the side-cover.
Fuel: A special blend of premix I drained out of the lawnmower.
Oh and of course I'd done the flapper mod.
Stock mufflers were removed and replaced with empty half kilo baked-bean tins. Sounds like the bells of hell :001_smile:
Side note - on the first attempt I also covered by buttocks in Vaseline, however I discovered it was impossible to stay on the seat over 30mph, plus with all that rubbing I'd aroused myself and I believe there was a certain amount of 'mast-drag' going on .......
I'll post pictures soon.
Oh and I highly recommend retaining the hugger if you are planning doing this as once you hit 160mph the Vaseline starts to liquify and you don't want that slippery stuff on the rear tyre.

This is excellent, and lots of laughs.
But I think you forgot to add in what was surely the last detail.
Didn't you reprofile the tire contact patches with a disc grinder to minimize the centre contact patch ? (So it would be like an ancient Dunlop 3.50 19 K81,?)
