I have 2 bikes each with cast & spoked wheels - each came with that as the only choice at the time. The TS had new stainless rims & spokes built for her and does very little mileage so there's no issues there. The 990 has the originals still in place and some spokes are a bit shabby looking where the chrome's suffering 10 years down the line, but everything is still tight & true.
Would I buy a spoked wheel bike again now if I had the choice? That depends who made it. Knowing the processed dairy products Suzuki use across their bikes, I wouldn't thank you for them as you know they're going to go wrong fairly quick. BMW ones you know aren't going to corrode as the dodgy drive train will keep them well oiled. KTM: well, there is the option of cast wheels that still look spoked and I would probably go for those if the option presented, but spokes wouldn't be a deal breaker.
