My ongoing garage clear out continues and I have got to the headlight box!
I have some Acerbis headlight units for sale on eBay. Although not specifically made for the TTR, they were taken off TTR250s that I broke for spares and put the headlights back "just in case".
If you are taking your TTR offroad for a Funday or similar where there is a risk of damaging panels then temporarily replace your original headlight with one of these
The price would be a lot less if it wasn't for postage, eBay and PayPal fees!
