The 2018 italian vintage championships starts soon so i took my 89 bikes out as they were unused since last summer. It was actually the first time i had my "standard" bikes facing each other same day, same track. My racebike with the aluminium VRP gas

I will only say this much: there's not much guys selling such parts let alone swingarms for every year... But as we can see you run the risk of having a rather expensive Banana holding your rear wheel. I wouldn't mount those parts unless you put the

I don't know for sure but i'd say yes - those were VRP parts. VRP also did HRC swingarms back in the day and still did aluminium parts for HRC in recent years.

In the VitalMX Pit Bits i just spotted the vented numberplate of Darian Sanayei's Kawasaki for the GPs....same basic idea again: draw air from behind the numberplate directly into the airbox (Ram-Air effect).

Well - at least to me it's pretty obvious the swingarm is not original but new made. I know from Mr. Verona (VRP) himself that he never used the stock, cast middle section to make his swingarms. Yet that guy sells all of his swingarms with the cast middle

Mugen kits enhanced power big time but it's all mid-top. If you are looking for bottom-end a 125 is not the way to go

BUT the 144 mod on the HPP is also not your best way to get more bottom as with the bigger bore you need to trim/shave ... more »

I just made yet another vented numberplate on my '89 Vintage racebike. Mine's not only for added cooling but actually also providing added airflow into the airbox as my '89 CR 125 has a italian VRP aluminium gas tank with two air tunnels that guide air

This treatment improves gas flow and improves throttle response. It is not just sanded but rather done with a very special, sharp edged grain. It is really ultra rough. Touching it feels like touching like 30 grade emery cloth. My friend too is a twostroke

Before i'd buy a Ti-shock spring ( i have it as well though

) i'd look into some lightweight seatfoam. On my CRF seat that was a 1 lbs saving for like 250$....while a Ti-spring costs about twice as much with similar savings. Similar savings ... more »

The intake parts of the 250 & 450 are fully interchangeable! However you need to order the whole airbox & that connecting tube. The exit of the airbox is not available separately. So you need the whole 450 airbox. The lenght of the connecting
