Both of my bikes popped up as "custom" bikes. I edited them and found the proper models. I think part of the problem is non-standard entries from the past. For example, Suzuki's LS650 was listed as a Suzuki Savage, as a Suzuki S40 Boulevard, and even as a manufacturer "Savage." There might be others, but I didn't spend much time looking. I feel sure that other long-lived models like the Honda Rebel and my 250 Star (nee Virago 250) have the same problem. My Majesty scooter could be listed as a 400 Majesty or as a YP400.
Same difficulty exists with cars. I believe I saw a manufacturer called "Abarth" even though it is really a Fiat. Someone would need an encyclopedic knowledge of different vehicle lines to straighten out the mess. And then there are cars like the former Pontiac Sunbird, which started life as a rear-wheel drive, then became a much smaller front-wheel drive while continuing with the same model name.
Too many models to count missing. I have my profile, but the 33 other bikes like mine are invisible. Looks like about 70% of the bikes that were a part of the "old" site aren't being shown in the new one.
