1986 BMW K75T
I think the K75T has been my favorite motorcycle (at least until the 2013 R1200R). I purchased it new in 1986 for $4850 ($5491 with freight, inspection, a windshield, one set of smaller "city" saddlebags, a larger set of touring bags, and a luggage rack). It has plenty of power, is fast enough, handles well, and gets decent gas mileage. Once again a new motorcycle prompted my brother and I to take a trip together (to Louisiana, Arkansas, and Missouri). Corrosion in the expensive aluminum tank (from water leaking into the tank through the gas cap) has been a common problem with these motorcycles, as has the speedometer.
- 750 cc four-stroke, three-cylinder, water-cooled, counterbalanced engine (see specifications below)
- Purchased new on March 25, 1986 from Lone Star Cycle Motive, Austin, Texas
- I still ride this motorcycle, which passed 38,000 miles in October 2011
- VIN: WB1057401G0130896
