THREE’S THE MAGIC NUM­BER

Motorcycle News (UK) - - THIS WEEK -

In­dian man­u­fac­turer Ba­jaj have pulled the cov­ers off their new Dom­i­nar 400, which fea­tures their DTS-I triple spark technology. Yes, three spark plugs, on a sin­gle-cylin­der bike. Aside from their own bikes, Ba­jaj also man­u­fac­tures the small ca­pac­ity KTMS, which is the source of the 390 en­gine in the Dom­i­nar. So how has it got three spark plugs? It’s much like you’d imag­ine – there are three spark plugs in the ig­ni­tion cham­ber, each giv­ing their own spark. Ba­jaj say this sig­nif­i­cantly cleans up the com­bus­tion stroke, and there­fore the ex­haust gases. The knock-on ef­fect of which is to re­duce the size of the cat­alytic con­verter re­quired, mak­ing the bike a lot cheaper to man­u­fac­ture and re­duc­ing bulk. The tech doesn’t end there ei­ther. There’s a full-colour TFT dash, au­toon LED head­lights and dual-chan­nel ABS, too. There’s no men­tion of the UK at the mo­ment, but the Dom­i­nar is on sale in In­dia for ap­prox­i­mately £1770.

‘Yes, three spark plugs, on a sin­gle­cylin­der bike’

Is this the world’s first mo­tor­cy­cle to have a triple spark plug head?
