The eastern ends of Routes 9 and 20 are traffic heavy, but 9 from Worcester west, and 20 especially west of Westfield, are beautiful roads. Nothing really twisty, but pleasant.
Route 16 west out of Wellesley is also nice. It meanders quite a while, then sorta disappears near the Conecticut line.
In the western part of Massachusetts, Route 8 and 8A, which run north/south, are very nice, with some reasonably-twisties in the vicinity of Becket. All the above offer generally good to currently-excellent pavement, too.
Also in the west, Routes 112 and 143 offer beautiful farm country and some good roads, but a couple weeks ago when I rode 112 south from Route 2, 112 was fine until I left its co-travel with Rt. 9 to continue south. There 112 was immediately of poorer pavement, uphill, and with heavy sand all down the middle and on both shoulders, left over from winter treatments. I decided "this doesn't look good; I'm too inexperienced to deal with this" and went right back to 9 west, which was great. There are a lot of roads in the west, the Berkshires, which are great bicycle or motorcycle rides. But I don't know of much really twisty, unless you were to make that happen by going fast, blindly on the curves, and over the speed limits.
Perhaps a general guideline might be to check good, detailed maps for secondary roads which follow rivers, such as the Westfield River or the Deerfield River in Massachusetts. These roads will meander with the rivers, so they're more interesting than simple 'connecting' roads, and often prettier.
This is the case with Rt. 20 going easterly from Lee to Westfield. Some fine, downhill twisties, which I enjoyed in my Fiat X 1/9, and still enjoy in my Madza Protege. Happy Riding!!
