Who owns the fastest XS11?

[trbig]

LOL.. I was talking about the Bob Jones ride a couple weekends ago... But I will be there in Fayetteville in Sept. barbecue, berr and pig trails... what could be better??

i know i missed the Bob Jones ride, that was my fault.....no excusses there....


The walk of shame........

fastest

iguess 134 should be fast enough i've seen 110 on a suzuki 70 on a honda 750 an83 on a 450 on a 50 i seen 32 miles per hour mph.

[jetmechmarty]

85 mph speedo

What is 7500 rpm in fourth gear? I have a Special with a stock final drive and stock tire size.

I observed that climbing Pine Mountain. I backed off to the posted speed limit before I crested the hill. As it turned out, there was a state trooper there waiting if I hadn't!

Hi all, im new here; Ive had my 11 to 200 km/h-about 124 mph?
5 mins later the front tyre blew out( luckely I had slowed down to about 50 mph---scary.I read a test years ago that XS1100's were good for 136mph in standard form?

[bobberbetty]

My bike is the fastest because,

1) its bare. ratted out. few high performance parts. -my secret. lol.

2) Im made out of lightnin.

I believe my neighbor has the fastest xs1100 in Westville Indiana (cuz its the only XS1100 in Westville) . Its an 81 standard. Needs LOTS of help. Trying to rebuild it for the old guy. I still to this day, even after launching Vmax's, cant get over the "bunny hop" that shaft drive bikes are noted for.....

[powerram50]

how the heck you guys go so fast?i have no windshield and at 80 my 140 lb ass is almost getting blown off the rear.

Bunny hop??????

These don't do the bunny hop, that's why the engine runs the opposite way than all the others. It eliminates the bunny hop. I suspect there's lots more fine things you don't know about the xs.

Running backwards

Hi Planedick,
Back in the 1930s New Imperial put a pair of reduction gears between engine & tranny unlike everyone else who used a chain drive. As the trannys of that era were concentric (the input and output turned the same way) the New Imp. engine had to be built to run backwards to compensate. A couple of decades later UJMs all have a pair of gears as a primary reduction but the UJM tranny is all indirect with the input and output tunning different directions. Thus the UJM engine turns forward. Now here come the Yamaha shafties which keep the all indirect tranny but no gears for them, they gonna use a Hyvo chain instead. And so the XS11 engine has to be built to run backwards to compensate. And just like the New Imperial, the backwards running engine precesses the wrong way as the bike leans over and just like the New Imperial you gotta fight the thing round corners.

[Guy_b_g]

Any engine precesses one way or the other. Precession on the XS11 would be to the right because the axis of the crankshaft is on the same plane as direction of travel, and the engine is turning clockwise.

Torque reaction would be a much stronger force, and it acts at right angles to the crankshaft and opposite to the direction of acceleration or deceleration, so on acceleration the torque reaction is toward the front of the bike, making it harder to wheely.

To me the biggest concern is the pinion gear trying to climb the ring gear, jacking the back of the bike up on acceleration and making the suspension act stiffer when you're on the throttle out of corners, causing wheel hop, or dropping you on a footpeg or some other low point on the bike when you chop the throttle in the corner..that's what causes most of the headaches when cornering IMHO.

No wind protecton either.....most comfortable speed I find is 60-70mph.

[lakecountrydave]

My 275 lb ass tends to stay where I put it. I would guess that the performance upgrade that would yield the greatest results that I could make would be to go on a diet. Luckily I already have the fastest XS11 so I think that I will check the fridge for a nice snack

I weigh 155, and bought a wind shield just for that reason. And the handle bars that lean me forward too.

I see guys on harleys kicked back like there in a lounge chair on the high way at 80 mph. If I lean back I go off the back! Or so it feels like. Or a gust of wind from a truck? Highway riding is kinda stressful for lighter folk. Got the constant death grip going on.
