Haven't figured this out yet

   I've been riding a long time, since 1974. I always had what I thought was the right bike at the time. Mostly Guzzi's but some others. My last bike was a 2020 V7 Racer that I still have but it's up for sale. I picked up a 2017 V9 Bobber that I feel like it's more age appropriate. I'm very comfortable on the bike, This will probably be the bike I ride into the sunset. But after 100 or so miles my thighs get tired. Not sore, just tired. I don't know why. I feel like I'm totally relaxed while riding. Maybe I just need more seat time.

The seat as well as the angle of your hips and knees might be altering blood flow to your legs. Small differences can have a larger effect. When I get that I just stand up for a minute or two while moving. Not hard to do unless you have clip ons.

The V9 Bobber has a very interesting seat... I would try a seat pad to see if having more shape to the seat helps.

I have just sold a 2027 V9 Roamer, essentially the same bike. The seat is terrible, narrow and thinly padded. Add pegs set well forward, and you end up with a riding position short on support, where you hang from your arms at speed and most muscles will be activated in order to keep your posture. Moving the pegs back will allow you to ride standing up easier for some relief, but also offer more support to fight the forces when riding normally. A wider, better padded seat will likely help a lot as well, and a decent windscreen should help a lot by keeping most of the wind off your torso.

I have just done the same thing after crashing my 1400 Eldo. The bike is in stellar condition for nearly 10 years old.  Having ridden 1400s and a V85 for the past 10 years, I always felt that the V7 series was cramped for me even though my inseam is only 29".  My dealer ordered the "Canadian/European" seat for me.  It is very similar to the current seat offered on the 850 V7 series. It adds about an inch to the height and is physically larger and longer an much more plush.  Also, I worked on rotating the bars to a good position for me. I use a short 12 inch windscreen currently. Finally, I added a Kaoko throttle lock. On Sunday, I came back from the 0hio Rally, a distance of 200 miles.  Between the 3 days, I logged about 600 miles. I found the bike to be a good traveler.  In the twisty roads near the rally, the lightness and nimbleness made the riding much more effortless than either of my 700+ lbs. 1400s.  It has a very usable torque range so less shifting is needed.  I will say though that after 200 miles in roughly 5 hours, I was ready to get off. It was less happy at 70 mph on the highway but would have run that speed until the tank went dry.  Backroads at 50-65 mph is really its happy zone in 5th gear.
About me: Age 67, health good, fat but not obese,5'8", 29 inch inseam. Today marks the 6 month anniversary of the crash and broken leg. Taking Tylonol 3 times a day for swelling from the leg.
I hope this is useful info for you as I think the bike was misunderstood when released but an excellent choice now for guys like us.

    I should have mentioned it has the Guzzi comfort seat. It is indeed comfortable, especially compared to the original stock seat. As I said, I'm comfortable and relaxed on the bike. It has the mid mount pegs, not the forward mount I think some came with. I'm thinking about sending the original plywood seat to Sargeant's to see if they can make it acceptable.

For years I worked with some of the leading IBA Rally riders.  I covered their custom seats from weather related damage.
They all said the same thing about comfort when we spoke.  The moved ever so slightly every 15 minuets to change pressure points.  Staying ahead of discomfort was their solution for 11 straight days of 1000 miles per day.  They ALL had seats made that let them move to multiple positions-never locked in.

I have found that they relationship of your body to the fixed points on the bike - footpegs & controls, tank, seat & handlebars to be critical factors for ling distance comfort. AND, minuscule adjustments can have significant effects.

I had had the V7 Claasic for some years & perhaps 100,000km before heading over to NZ for the Burt Monroe (& the Norton Owners rally), for which I purchased an 1100 Sport. You might know the bike - all engine on a couple of wheels, full fairing, high pegs set rearwards & a long reach over the tank to the bars. Looks to be an uncompromising position. The first 4 hour run from Napier to Wellington seemed to stretch every bone, tendon & ligament on fire, but after a long hot shower & a deep sleep that night, absolutely no aches, pain or discomfort at all. The whole trip. I was very impressed. For me, THE MOST COMFORTABLE LONG DISTANCE TOURER I had ever ridden - better than the CX500.

The majority of the weight was on the feet & the knees gripping the tank a little on the pelvic bone on the seat, no weight at all on the bars, and the backbone & neck in a straight line while looking at the road ahead. I figured (opined) that having no tension in the back & neck was the secret.

As soon as I came back home I set out to replicate that riding position on the V7C as best I could. Racer rear sets (3 position adjustable, plus the toe piece on a cam), & Jota-style handlebars with multiple adjustment capability. It took a lot of fiddling around, especially with the handlebar positioning, I would set up a likely positioning, then do a 500km test run, over & over, until there was no discomfort or twinges or tiredness by riders end.

It worked - not as comfortable as the 1100 Sport, but close. Most weight on the footpegs (I've always ridden with the balls of the foot on the pegs) & none on the handgrips, and the back & neck straight. Good for comfortable all day riding.  Got rid of the screen - air seemed to stream over the lip straight onto the visor on the helmet, & so buffet the head. Best without that screen.

Conclusions:
. Having the back & neck in a straight line enables relaxed all day riding.
. The resulting slight forward lean appears to avoid any air/wind pressure.
. Less weight on the hands helps keeping the body relaxed & reduces tension.
. Handlebar positioning is crucial.
. The seat became pretty much irrelevant - I still prefer the solo Racer seat, but the stock double plank or the so-called "comfort" seat is fine as well. I use the more plush "comfort" double seat when need luggage on the pillion space.
. Every body is different, and articulates differently. Bodies can & do adjust with practice &/or exercise, but it's best to start somewhere close to your comfort limits.
. The multiple adjustments needed for comfort are well worth the effort.

In your case, tension in the thighs may be (at a rough guess) a function of the toe to heel movement required to operate the foot controls, while your body is set in an unfamiliar/different riding position. I would try experimenting with the position of the gearshift & brake on their splines, & see what you can do with the position of the footpegs. Experiment with various seat pads & seats. Play with the handlebar angles - everything affects/relates to the whole. Good luck.

I had a Corbin for a while. The only way I could go more than a few miles was with an AirHawk and a sheep skin on top of that. It did raise me up to setting in a higher position. discovered Russell seats and it was a cure. They usually raise you up an inch or more.

The basic concept is to get your joints (hips, knees, ankles) angles opened up. Try to get the joint angle opened as far from 90° as feasible.

   Malik, I had a 96 1100 Sport. I put 124,000 mikes on that bike with many 700 mile days. All day comfortable after I flipped the handlebars upside down and left for right. But I was much younger then.
