1968 BMW R60

BMW is not the first name you think of when you want to make a Café racer, the Earles Fork models from 1955-1969 would be even less likely to be chosen. But this is exactly what has been done to this 1968 R60/2 BMW offered up on eBay now. “Making it work” was a difficult thing to accomplish, but the builder of this bike has done a very good job.

From the seller

This is a1968 R60/2 matched numbered machine that has been Hand Made into a tribute to the famous Racing machines of the 50’s. This bike is a testament to the Famous Cafe Racing BMW’s Rennsport’s of the late 50’s and 60’s.

Modified frame with custom rear sets.  Totally custom front end with a Rare and Famous Grimeca Italian leading four shoe front brake, Dellorto Carborators along with a lightened flywheel and higher compression pistons.

The Megura clip-ons with custom triple tree hold the rare Competition/Police Hella Period Headlight Bucket, without a speedometer. Next to that is a VDO tachometer drive system, All accessories are genuine  no reproductions were used.

From 1955 until 1969 BMW offered this 594cc R60 as a work horse of a motorcycle. With the Earles forks up front, and a sidecar attached, the R60 would be used as daily transportation for a small family. Larger in displacement then the R50/2, and without the high compression engine of the R69S, the starting point of this Rennsport inspired bike is and interesting choice. There are some that believe that the combustion design of the “lesser” R50/R60 heads have more potential then the Hemi shape of the R69S heads. From the factory the R60 only generated 28hp at 5800rpm which gave it a top speed of 90mph. Stock compression ratio would only have been 6.5:1, so there is lots of room to improve. I would hope with the addition of Dellorto carbs, and removal of the big chunk of aluminum from the transmission that is the air cleaner mounting point,  hint toward other engine modifications the seller does not point out.

More from the seller

Tank is a period collectible Hoske, approximately 8 gallons, it is perfect inside and out. The seat is a custom Cafe style and both fenders are Stainless. Rear tail light is a Dami Racer. Rims are alloy with stainless spokes. The final drive has been polished as well.

This custom motorcycle, is a joy to ride, since its creation it has less than 1,000 miles on the road.

The Black bikes from Bavaria have always been seen as a rich, boring mans bike. High bars, big seats, and the shaft drive are all designed to get you from where you are to where you want to be. Nothing more. The truth is that BMW from this era have a cult like following often more interested in re-creating the same bike that came out of the factory those many years ago. This is not one of those people, they asked what if, and then went and did it. This R60 BMW is not your older, conservative, fathers bike. Will it be one that you place a bid on? BB

1985 BMW K100RS

So what is the demographic targeted by a Sports Touring motorcycle? People that want to go fast but have stuff to carry? People that want to go fast, but comfortably? People that want to go fast in the twisties, but not on their hands? Anyone that doesn’t want a classic American Cruiser? This is who BMW targeted when they designed their sports touring bikes, and this 1985 K100RS (Reisesport) offered on eBay was a major change in the 60 years history of the maker.

The K series of bike left the traditions of BMW behind, and almost left their core fans. An in line 4 cylinders laid on its side compared to the opposed twin Boxer. Liquid cooled compared to air cooled. Fuel injection compared to twin carburetors. Shaft drive compared to shaft drive. Ok that last one not so much.

The seller of this Brick has very little to say

For Sale is a 1985 BMW K-100 RS, under 10K miles.  Dealer Serviced and Heated Storage since New, Second Owner.  Has New Metzler Tires, WestCo Gel Battery, BMW Hard Bags, Top Case, Battery Tender.

Like New, Mint, None Nicer

What you do get in the way of sport is 983cc of 10.2:1 CR giving you 90bhp that will push the 548 lb bike (plus what ever you can stuff in the bags) to a top speed of 136 mph. If you had waited for the 1989 model you would have gotten 2 more valves per cylinder and 10 more HP and 6 more mph. The sport is defined by the size of the fairing, on the RS, a small compact fairing that may remind you of the bikini fairing of the R90S. Stepping up in Touring and away from Sport you would get the RT and then the pinnacle of luxury, the LT.

If you are someone that wants to be comfortable on your classic, and want modern (for the 1980’s) stylings, the K100RS might be the bike for you. But be prepared to possibly get a cold shoulder (air cooled?) from other Real BMW riders.

1962 BMW R69S Rennsport Replica

Whenever you see Rennsport attached to a BMW motorcycle you are supposed to remember BMW’s great racing history. Though this history is mostly before 1939 with the RS54 and achieved using supercharged engines, it is there and it does inspire BMW owners like myself.

The R69S was the Sport model from 1955-1969. It came from the factory with a sportier cam and high domed “Hemi” pistons, which gave it a 9.5 CR and 42 hp.

From the seller

  1962 BMW R69S Rennsport Replika, A Perry Bushong Rennsport replika based on a 1962 R69S evocative of the 1954 race bike built very limited numbers for racing.

The tank is larger then stock and made by Ernst Hoske. If you search long and hard you can also , or even find the Hoske name on mufflers, oil pan extensions and (on my personal wish list), Hoske wheels.

The Tachometer is also an upgrade that many BMW riders look for and are being reproduced so they are less difficult to find. The front wheel appears to be from a Suzuki GT750, a heavy but affordable four leading shoe brake. Along with the rear-sets the 4LS is a requirement to be a  racing replicas. Carburetion is upgraded from the 26mm Bing’s with what appear to be Dellorto or Keirn with air-pods, but not the sexy velocity stacks. Displacement from the factory was 72mm x 73mm for 594cc, so I am not sure that the quoted 690cc is accurate. There were big bore kits available, but they bumped the motor up to 750cc.

The asking price of $27,995 is high, but the text leaves it open to whether the bike is for sale or not.  BB
