For anyone who is lurking and looking for the same information, here's what I've come up with so far.
My research included:

Cabarete Dominican Republic
What I've found:
Motocaribe
MotoCaribe Motorcycle Adventure Tours (no individual rentals, organized tours only)
Very professional and prompt response. On their website you can get an e-book titled "Two Wheels In Paradise, A guide to riding motorcycles in the dominican republic". Very useful for those who've never ridden in less develloped countries, and a good reminder for those who already have some experience in that area. Well balanced advice from those who've done it and are still doing it. These folks run their tours on Suzuki V-Strom 650's (Dual sport bikes). Based out of Jarabacoa. Closest international airports: SDQ, STI
Dominican Riders
Dominican Riders (no individual rentals, tours only)
Also a very prompt and professional response. Their tours are on large displacement Harley Davidson cruisers. Base in Punta Cana. Closest international airport: PUJ
Cabarete Enduro Tours
Cabarete Enduro Tours - Cabarete, Dominican Republic
KTM offroad bike tours. I did not contact them since my short legs simply don't work with KTM bikes. By the looks of it they offer true offroad day tours. Closest international airport: POP
Easyrider Cabarate
fahren Sie mit der Nr. 1 an der Nordk?ste !
The only company I could find online which does individual rentals. They have Yamaha 125cc offroad bikes and Yamaha scooters, along with car rentals.
I have unfortunately not had any luck getting in touch with them. Two emails and a phone call and I'm still waiting for a response. Closest international airport: POP
According to a thread on advider.com as well as a suggestion by the staff at Dominican Riders, it shouldn't be a problem to just head to Sosua, Cabarete or Las Terrenas and rent one on the spot. It was also suggested to bring one's own riding gear, including helmet if you decide to rent on the spot.
While not motorcycle related this site could be useful for general independent traveller information.
El Pedalero: Life, on a bike, in Latin America : El Pedalero. This fellow bicycles Latin America, including the DR.
My own rather out of date blog (
www.scrabblebiker.com) will be updated during my upcoming trip and anyone who wishes to contact me privately for genuine independent travel questions can do so on ADV Rider, Horizons Unlimited or DR1
I hope someone will find this information useful.
Buen viaje y buena suerte.
