I took the R100GS to the shop to get a $6 spring replaced in the transmission and some new fork springs. $150 in parts and nearly $1200 in labor. When I spoke to the shop last, they told me that the fork tube had cracked and that they had been looking for a used one. Another $300 for a new tube. They were only able to find a questionable pair - they were off a bike with front-end damage and powder coated black. The guy didn't want to split the pair either. BMW NorthAmerica had none in stock so they had to order a new one von Deutschland. They couldn't estimate the delivery date much better than 'within a week or two'.
