And funny you mention XRs , I have more fun on a kitted out 123cc XR100 on a Motard ( kart) track than should be legal
And safer than big stuff, so you can afford to be aggressive as hell. That's why I love it.
I had a bare bones machine 123 XR that needs a crank and have a 150cc Frank Nye stroker I was flat tracking and will sprint, now with TMGP. The KX had 17s and 125 rubber, big disc, appropriate rims, all bikes have Linderman suspension. Big, big fun on little tracks. The little KX is like a motoGP scaled down, little power wheelies off corners, big slides. It's a hoot. Won a lot of races with it. But, they cut down on the classes for the KX, thus I retired it and started building yet another XR with the front end off the two stroker. I rid myself of TZs many years ago. Hell, the 125s I was riding are as fast now days as the 250s were when I was riding them. I had a D model monoshock with an F model Kanemoto top end and a B model cases/tranny and Lectron powerjets and, well, it was piecemeal, but it was fun. Did RDs before the TZ stuff.
Actually, I haven't been back to the track in a year. I've had too many of other peoples stuff to fix, work on small engines in retirement. I'm going to get something going for next year, though, dangit! LOL
I get in the ATGATT arguments with others. It's danged hot down here and I ride every day for transportation, even hauled my XRs to the track behind my old Gold Wing on a flat bed trailer. I've even gone goose hunting on the wing using a trailer to haul the gear. I've been riding since 13, shooting since 6, so I like to combine the two as much as possible.
I'll do a squirrel trip to the piney woods now and then, usually take my Contender/.22 match barrel, 2x optic in a saddle bag, but now I have this Ruger Mk2 with an optic that's fun and accurate enough, 1" at 50 yards accurate. Deer hunting off the bike is a bit much, hauling coolers and such, so I stick to birds and small game and have guns I can fit in my bags. Latest is a 10 gauge H&R turkey, 24" barrel, just fits in the top box of the old Wing when taken apart. It's my goose gun.
Back on direct topic, I originally bought a Mitch Rosen Workman IWB tuckable to keep the shirt tail from flying up on me. The guy with the wing mentioned he sits on his shirt tail. That works on the wing, but on the SV, even though I have a set of Honda Hawk bars on it that sits me up a little better, any sport bike, your shirt tail rides up a bit and you can't sit on it. Even with my armored mesh or heavy winter riding jacket on, I don't want my shirt tail riding up over the gun. SO, pocket carry just seems logical to me. I usually carry my Kel Tec P11 right front pocket and one reload on the belt. If I fall on it, it won't break anything and probably would save me a little rash.
The one thing that screws up the pocket carry thing is if I have a rain slicker on. But, I can get to it if OFF the bike and I see no reason to get to it ON the bike. I bought this pair of waterproof armored riding pants some time ago, but have only worn 'em once. It's got to be pretty cool out of they'll COOK you. They have a big enough pocket on 'em for the P11. I had some "draggin' jeans" for a while, but the pockets are too small on those things. They didn't really fit good, anyway, so I sold 'em on a MC board.
