Momos Forza 135

BikerVoodoo reader Al sent in these pics of the “Rocket Boy” by Tiger Motorcycles of Thailand. Al says, “Not sure if this is the Momos Forza, but it looks like the only minibike Tiger company has. If it is, I’m buying one. Supercool! Trellis frame, single sided swingarm, chain through swingarm.” His only concern is that parts might be a problem unless Mofaz, the Malaysian distributor of Tiger Motorcycles (built under licence in Malaysia under the “Momos” brand) brings in lots of spares. The Rocket Boy is being sold in Malaysia as the “Momos Forza”.

The Rocket Boy looks like a Kawasaki KSR110 on steroids. Compared to the KSR, the Rockey Boy is powered by a 135cc single cylinder, 4-stroke SOHC engine, fed by a PZ20 26mm carb. That’s 25cc’s more than a KSR110, although you can buy a big bore kit for the KSR from Takegawa to bump displacement up to 138cc. Other tuning suppliers sell even higher displacement piston/cylinder kits. The Tiger Rocket Boy has a rear monoshock and 4-speed tranny just like the KSR, but with a manual clutch, unlike the centrifugal clutch on the KSR. Unfortunately it falls short by having a fuel capacity of only 4 litres, whereas the KSR holds 7.3 litres in its midget Supermotard styled tank.

Haven’t heard of Tiger? Here’s a short background story on one of the world’s most mysterious motorcycle makers. Apparently Tiger Motorcycles was formerly associated with the Italian make Cagiva and produced Cagiva-branded motorcycles in Thailand. This has always been a big mystery and nothing has been published online about the Tiger-Cagiva story. I found out through Thai media contacts that Cagiva came to Thailand as a result of Porntip Narongdej, a Thai Yamaha distributor’s relationship with the Claudio Castiglioni, owner of Cagiva in Italy. Narongdej’s Yamaha setup provided the infrastructure for dealerships and logistics at a time when only Honda, Yamaha, Suzuki and Kawasaki sold in Thailand. I believe at one time the Thai government had an investigation of industry in Italy, and one of the fruits of this investigation was the Tiger Motorcycles (I think!) & the Cagiva relationship. This has now sadly ended, and one of the last joint efforts was the Cagiva F4, which was eventually produced and sold as the Tiger Boxer ST200 (Momos Boxer in Malaysia).

The Tiger-Cagiva setup resulted in one of the most powerful 2-stroke cub-style mopeds known to mankind, the Cagiva Stella 125R, which was powered by a 125cc 2-stroker with CTS (Cagiva Timing System), producing 23.5PS at 10,300rpm! That, is another story.
