<![CDATA[ATHENA 170cc]]>I plan on keeping my TDR for a long time and i'm changing rings at the moment and noticed my bore has some lights scratching and signs of wear. Was thinking of getting the Athena 170cc kit at some point in the future, does anyone know if they are worth the money, not really looking for a big boost in HP but is a bit of Torque would be nice and is the quality as good as original Yamaha
Thanks

Was very reliable.

Stock work fine with me.

I got a nice improvement in mid and (especially) low rev range torque. I never get tired of cruising along at just over 5K~RPM doing 60mph nice and lazily…

I’m sure a bigger carb would be a boon, but myself I hardly ever go over half~3/4 throttle, so it’d be wasted on me 😜
I kinda think if you love WOT revving the nuts off of it, it’d be better sticking with the 3MB barrel…

To get the most out of the Athena you'll want a bigger carburettor. I run the VHSA out of the TZR 4DL Belgarda.

Thanks again

Zeeltronic is excellent as @Calum said.
You can "play" nice with Yamaha's CDI from other models if you want or some unrestricted.
@Calum has done extensive mods the other members mentioned from him have their respected history also,I will add @SpookDog and @Louis-DT-WR.

Probably done every modification under the sun and back again. So I know a little more than average about them. True masters are people like @oldman @scrimsmustang @HOTSHOT-III to name a few.

Yeah, I've grown to like the Athena I must admit. If you go back 10 years, you'll find posts of me not loving it so much. The reason is, my friends all had Aprilia RS125s and they just run rings around the DTRs. The fact is, I wanted something like a YZ or Aprilia in terms of performance.

I've now grown to realise that the DTR was never going to be on par with those bikes, no matter how much I spend. So now it's just about appreciating the DTR for what it is. The Athena is more akin to my type of riding, when I'm on my DTR.

When I'm on my RS, it's all about revving the nuts off of it 😛

There is a huge loss of over-rev, but the midrange is brilliant. Dies off around 10,000RPM.

Couple this with a pipe and a proper ignition system then you're in for a real treat.

The bore is nikasil plated and the head is independent from the skull cap. So overall it's nice quality.

I had mine ported by Mick Abbey as well.
