Hey, Mr VTX! XHombre here... another denizen of the VTXOA and also a former owner of two VTX 1800s.
I think I noticed an 1800 for sale over in the OA's classifieds that looks nearly identical to your 1300. Same color, screeen and bags, I think? It had me drooling.
It was a very tough decision to opt out of getting a third VTX for the R3 that I ultimately bought. No regrets, however I would not hesitate to have another big Honda, if there was room in my garage and if the Mulberry Mistress promised not to get jealous!
